And the tree of the field shall yield her fruit, and the earth shall yield her increase, and they shall be safe in their land, and shall know that I am the LORD, when I have broken the bands of their yoke, and delivered them out of the hand of those that served themselves of them.
They ... shall know that I am the Lord, when I have ... delivered them out of the hand of those that served themselves of them - "served themselves of them," availed themselves of their services, as if the Jews were their slaves (Jeremiah 22:13; Jeremiah 25:14: cf. the bond-service of Israel to the Egyptians, Genesis 15:13; Exodus 1:14).
