Cross-reference

Jeremiah 25:27 contains another divine command to the same nations to drink the cup of wrath—a parallel message of submission to judgment.

Jeremiah 28:14 repeats the same 'Thus says the LORD of hosts, the God of Israel' formula later in the same prophetic context.

Exodus 5:1 Parallel

Exodus 5:1 uses the identical 'Thus says the LORD, the God of Israel' formula when Moses confronts Pharaoh, reinforcing the divine authority behind Jeremiah's message.
