Psalms 25:9 He guides the humble in judgment; and he teaches the humble his way.
Humility is requried. Superiority is rejected. That is the way.
So, the covenant is eternal just as God is eternal. Leviticus 26:43-44
The land also shall be left by them, and shall enjoy her sabbaths, while she lies desolate without them; and they shall accept the punishment of their iniquity; because, because they despised my judgments, and because their soul loathed my statutes.
And yet for all that, when they are in the land of their enemies, I will not cast them away, nor will I loathe them, to destroy them utterly, and to break my covenant with them; for I am the Lord their God.And yet ... I will not ... break my covenant ... for I am the Lord their God. That is an eternal covenant. Unbreakable.
Psalms 37:11 But the humble shall inherit the earth; and shall delight themselves in the abundance of peace.
