If possible, do you have translations of these texts? Or is this coming from commentary of others?
Much further upstream, I provided you with a direct translation of the Sefer Hekhalot.
It was from Charlesworth's Pseudepigrapha:
The Old Testament Pseudepigrapha
The Melchizedek scroll (11q13) from Qumran. Here are two different English translations:
1 […] your God … […] 2 […] And as for what he said: Lev 25:13 <<In this year of jubilee, you shall return, each one, to his respective property>>, as is written: Deut15:2 <<This is 3 the manner (of effecting) the [release: every creditor shall release what he lent [to his neighbour. He shall coerce his neighbour or his brother when] the release for God [has been proclaimed]>>. 4 [Its inter]pretation for the last days refers to the captives, about whom he said: Isa 61:1 <<To proclaim liberty to the captives.>> And he will make 5 their rebels prisoners […] and of the inheritance of Melchizedek, for […] and they are the inheri[tance of Melchi]zedek, who 6 will make them return. He will proclaim liberty for them from the [debt] of all their iniquities. And this will [happen] 7 in the first week of the jubilee which follows the n[ine] jubilees.
And the day [of atone]ment is the end of the tenth jubilee 8 in which atonement will be made for all the sons of [God], and for the men of the lot of Melchizedek. [And on the heights] he will decal[re in their] favour according to their lots; for 9 it is the time of the <<year of graces>> for Melchizedek, to exa[lt in the tri]al the holy ones of God through the rule of judgement, as it is written 10 about him in the songs of David, who said: Ps 82:1 <<Elohim will stand up in the assem[bly of God,] in the midst of the gods he judges>>.
And about him it says: Ps 7:7-8 <<Above it 11 return to the heights, God will judge the peoples>>. As for what he sa[id: Ps 82:2: <<How long will yo]u judge unjustly, and show partiality to the wicked? Selah.>> 12 Its interpretation concerns Belial and the spirits of his lot, who were rebels [all of them] turning aside from the commandments of God [to commit evil]. 13 But, Melchizedek will carry out the vengeance of God's judgements [on this day, and they shall be freed from the hands] of Belial and from the hands of all the sp[irits of his lot.] 14 To his aid (shall come) all <<the gods of [justice>>; he] is the one [who will prevail on this day over] all the sons of God, and he will pre[side over] this [assembly].
15 This is the day of peace about which God spoken of old through the words of Isaiah the prophet who said: Isa 52:7 <<How beautiful 16 upon the mountains are the feet of the messenger, who announces peace, of the mess[enger of good who announces salvation,] saying to Zion: ‘Your God [reigns>>.] 17 Its interpretation: the mountains are the prophets … 18 And the messenger is [the ano]inted of the spirit, whom Dan[iel] spoke … and the messenger of good who announces salv[ation is the one about whom it is written that [he will send him Isa 61:2-3 <<to comfo[rt the afflicted, to watch over the afflicted ones of Zion>>.] 20 To com[fort the afflicted, its interpretation:] to instruct them in all the ages of the world… 21 in truth […] 22 […] it has been turned away from Belial and it […] 23 […] in the judgements of God, as it is written about him: Isa 52:7 Saying to Zion" "Your God rules". Zion is the congregation of all the sons of justice, those] who establish the covenant, those who avoid walking [on the pa]th of the people. Your God is Melchizedek, who will free them from the hand of Belial. And as for what he said: Lev 25:9 You shall blow the horn in every lands. (Florentino Garcia Martinez, The Dead Sea Scrolls Translated: The Qumran Texts in English [William B. Eerdmans, Grand Rapids MI 1996], pp. 139-140)

15 This is the day of peace about which God spoken of old through the words of Isaiah the prophet who said: Isa 52:7 <<How beautiful 16 upon the mountains are the feet of the messenger, who announces peace, of the mess[enger of good who announces salvation,] saying to Zion: ‘Your God [reigns>>.] 17 Its interpretation: the mountains are the prophets … 18 And the messenger is [the ano]inted of the spirit, whom Dan[iel] spoke … and the messenger of good who announces salv[ation is the one about whom it is written that [he will send him Isa 61:2-3 <<to comfo[rt the afflicted, to watch over the afflicted ones of Zion>>.] 20 To com[fort the afflicted, its interpretation:] to instruct them in all the ages of the world… 21 in truth […] 22 […] it has been turned away from Belial and it […] 23 […] in the judgements of God, as it is written about him: Isa 52:7 Saying to Zion" "Your God rules".

And here is the alternate translation:
II … And concerning that which He said, In [this] year of Jubilee [each of you shall return to his property (Lev. xxv, 13); and likewise, And this is the manner of release:] every creditor shall release that which he has lent [to his neighbour. He shall exact it of his neighbour and his brother], for God’s release [has been proclaimed] (Deut. xv, 2). [And it will be proclaimed at] the end of days concerning the captives as [He said, To proclaim liberty in the captives (Isa. lxi, I). Its interpretation is that He] will assign them to the Sons of Heaven and to the inheritance of Melchizedek f[or He will cast] their [lot] amid the po[rtions of Melchize]dek, who will return them there and will proclaim to them liberty, forgiving them [the wrong-doings] of all their iniquities.
And this thing will [occur] in the first week of the Jubilee that follows the nine Jubilees. And the Day of Atonement is the e[nd of the] tenth [Ju]bilee, when all the Sons of Light and the men of the lot of Mel[chi]zedek will be atoned for, [And] a statue concerns them to provide them with their rewards. For this is the moment of the Year of Grace, for Melchizedek. And he will, by his strength, judge the holy ones of God, executing judgement as it is written concerning him in the Songs of David, who said, ELOHIM has taken his place in the divine council; in the midst of the gods he holds judgement (Psalms lxxxii, I). And it was concerning him that he said, (Let the assembly of the peoples) (Psalms vii, 7-8). As for that which he s[aid, How long will judge] judge unjustly and show partiality to the wicked? Selah (Psalms lxxxii, 2), its interpretation concerns Belial and the spirits of his lot [who] rebelled by turning away from the precepts of God to … And Melchizedek will avenge the vengeance of the judgements of God … and he will drag [them from the hand of Belial and from the hand of all the spirits of his lot. And all the ‘gods of Justice’ will come to his aid to attend to the de[struction] of Belial. And the height is … all the sons of God … this … This is the day of [Peace/Salvation] concerning which God spoke through Isaiah the prophet, who said, [How] beautiful upon the mountains are the feet of the messenger who proclaims peace, who brings good news, who proclaims salvation, who says to Zion: Your ELOHIM reigns (Isa. lii, 7). Its interpretation; the mountains are prophets … and the messenger is the Anointed one of the spirit, concerning whom Dan[iel] said, Until an anointed, a prince (Dan. ix, 25)] … And he who brings good [news], who proclaims salvation; it is concerning him that it is written … To comfort all who mourn, to grant to those who mourn in Zion (Isa. lxi, 2-3). To comfort [those who mourn: its interpretation, to make them understand all the ages of time … In truth … will turn away from Belial … by the judgement of God, as it is written concerning him, who says to Zion; your ELOHIM reigns. Zion is… , those who uphold the Covenant, who turn from walking in the way of the people. And your ELOHIM is Melchizedek, who will save them from the hand of Belial.
As for which He said, Then you shall send abroad the trump[et in] all the land (Lev. xxv, 9) … (The Complete Dead Sea Scrolls in English, translated by Geza Vermes [Penguin Books, Revised edition 2004], pp. 532-534)
