with whom the Lord had made a covenant and commanded them, saying, “You shall not fear other gods or bow yourselves to them nor serve them, nor sacrifice to them.

And the Lord was with Hezekiah; he was successful wherever he went. And he rebelled against the king of Assyria and refused to serve him.

Gedaliah swore [an oath] to them and their men, and said to them, “Do not be afraid of the servants (officials) of the Chaldeans. Live in the land and serve the king of Babylon, and it will be well with you.”
