1 Chronicles 19:15

And when the children of Ammon saw that the Syrians were fled, they likewise fled before Abishai his brother, and entred into the city. Then Ioab came to Ierusalem. 1 Chronicles 19:15 (KJV)

Historical context: The events described in this verse take place during the time when David was king of Israel. The Ammonites, who lived east of the Jordan River, had hired mercenaries from Syria to help them in their battle against Israel. When the Syrians fled, the Ammonites retreated into a city. However, when the Syrians saw that they were losing, they fled from the battlefield, and the Ammonites followed suit.

The role of Abishai: Abishai was one of David’s nephews and a prominent military commander in Israel. In this verse, it states that the Ammonites fled before Abishai, indicating that he played a significant role in the defeat of the Ammonite forces. Abishai was known for his bravery and loyalty to David, and he often fought alongside his brother, Joab.

The entry into the city: After the Ammonites fled before Abishai, they sought refuge within a city. The verse does not specify which city they entered, but it indicates that they were no longer a threat on the battlefield. This retreat marked a victory for Israel.

Joab’s return to Jerusalem: Joab, the overall commander of David’s army, returned to Jerusalem following the battle. Joab led the battle, and after securing their defeat, he returned to Jerusalem. This suggests that Joab entrusted the pursuit of the Ammonites and the securing of their defeat to his brother, Abishai, while he himself returned to report to David in the capital city. Joab, identified as the overall commander of David’s army, is said to have returned to Jerusalem following the battle.
