Quick answer

The people ask how to tell which message truly comes from the LORD. God anticipates the practical need to discern true from false prophecy.

Overview

Recognizing the danger of false prophets, the people wonder how they can know whether a word is really from God. The question is honest and important, and God graciously gives a test in the next verse. It reminds us that God expects His people to discern and test what claims to be His word.

Christ at the center

Moses promised a Prophet like himself to whom Israel must listen (18:15); Jesus is that Prophet, the one who keeps the covenant we broke and becomes the curse for us by hanging on a tree (Gal 3:13).
