24 Now Saul committed a very rash act on that day. He had laid an oath on the troops, saying, "Cursed be anyone who eats food before it is evening and I have been avenged on my enemies." So none of the troops tasted food.

Matthew Henry's Commentary on 1 Samuel 14:24

Commentary on 1 Samuel 14:24-35

(Read 1 Samuel 14:24-35)

Saul's severe order was very unwise; if it gained time, it lost strength for the pursuit. Such is the nature of our bodies, that daily work cannot be done without daily bread, which therefore our Father in heaven graciously gives. Saul was turning aside from God, and now he begins to build altars, being then most zealous, as many are, for the form of godliness when he was denying the power of it.
