Exodus 23:32

Thou shalt make no covenant with them — i.e., no treaty of peace; no arrangement by which one part of the land shall be thine and another theirs. (Comp. Exodus 34:12.)

Nor with their gods. — It was customary at the time for treaties between nations to contain an acknowledgment by each of the other’s gods. (See the treaty between Rameses II. And the Hittites in the Records of the Past, vol. iv., pp. 27-32.) Thus a treaty with a nation was a sort of treaty with its gods.
