They said to the messengers who came, Thus shall you tell the men of Jabesh Gilead, Tomorrow, by the time the sun is hot, you shall have deliverance. The messengers came and told the men of Jabesh; and they were glad.
Saul wisely divided his troops into three companies. He attacked the besieging Ammonites early in the morning. The morning watch was the last of three night watches, and it lasted from about 2:00 to 6:00 a.m. These three watches had their origin in Mesopotamia, but all the western Asian nations observed them before the Christian era (cf. Lamentations 2:19; Judges 7:19). The only other place in the Old Testament where this phrase "at the morning watch" occurs in Hebrew is Exodus 14:24. Then God slew the Egyptian soldiers as they pursued the fleeing Israelites through the Red Sea. Perhaps the writer wanted his readers to view this victory as another miraculous deliverance at the beginning of a new phase of Israel’s existence.
