When David was close to death, he told Solomon his son:

“Treat fairly the sons of Barzillai of Gilead and provide for their needs, because they helped me when I had to flee from your brother Absalom.

May the Lord our God be constantly aware of these requests of mine I have presented to him, so that he might vindicate his servant and his people Israel as the need arises.

The armies were deployed opposite each other for seven days. On the seventh day the battle began, and the Israelites killed 100,000 Syrian foot soldiers in one day.
