No matter the text that there was in the time of Moses because NO LONGER EXISTS. The earliest texts we have are in Greek, not Hebrew. The Hebrew texts are translations of Greek texts, and many times very bad translations.
You aren't listening to what the prophets have said, because they said that God's law was changed. God's Law was changed. This was announced by the prophets. Not only does the prophet Jeremiah said that the Law had been changed. Other prophets also said it:
"...but my people know not the ordinance of the LORD. "How can you say, 'We are wise, and the law of the LORD is with us'? But, behold, the false pen of the scribes has made it into a lie". (Jeremiah 8:7-8)
"Woe to those who give wicked laws and scribes who write tyrannical prescriptions to set aside the poor and violate the rights of the underdog of my people, to rob widows and orphans" (Isaiah 10.1 -2)
"And the land is defiled under its inhabitants, because they have transgressed the laws, changed the commandments, broken the everlasting covenant" (Isaiah 24: 5-6).
"Her prophets are light and treacherous persons: her priests have polluted the sanctuary, they have falsified the law". (Zephaniah 3:4)
" My covenant was with him of life and peace........ The law of truth was in his mouth....... But ye are departed out of the way; ye have caused many to stumble at the law; ye have corrupted the covenant of Levi, saith the LORD of hosts" (Malachi 2:5-8)
And Jesus Christ, remembering the words of the prophet Isaiah, also told the scribes and Pharisees who were teaching the commandments of men:
"Hypocrites, well did Isaiah prophesy of you, saying,
This people honors me with their lips;
But their heart is far from me.
But in vain they do worship me,
Teaching for doctrines commandments of men" (Matthew 15.7-9
Dear friends, this is what happened, what the prophets tell us: The God's law was changed by the scribes. For this reason, the Old Testament's law is different to the commandments of Jesus Christ.
Jesus Christ gave us the true Law that God gave to Moses.
