-### Structure and formatting
-
-Some translations set poetry farther to the right than the rest of the text to show that it is poetry. The ULB does this with the poetry in 21:14-15, 17-18, 27-30.

-#### Ungrateful
-
-The Israelites said, "Why have you brought us up out of Egypt to die in the wilderness? There is no bread, no water, and we hate this miserable food." After all Yahweh had done, they were very ungrateful. This showed their lack of faith and trust in Yahweh. (See: [[rc://en/tw/dict/bible/kt/faith]] and [[rc://en/tw/dict/bible/kt/trust]])
