Final answer:
The kingdoms of the surrounding countries witnessed the victories of the Hebrews under their kings when they heard that the LORD fought against their enemies.
Step-by-step explanation:
When the kingdoms of the countries surrounding Israel heard that the LORD fought against the enemies of Israel, it refers to the biblical accounts of the victories won by the Hebrews under the leadership of their kings.
For example, in the early years, the Hebrews faced conflicts with the Philistines, who were one of the groups known as the 'Sea People.'
Initially, the Philistines, armed with iron, fought the Hebrews to a standstill, but under the leadership of their kings, the Hebrews were able to push back and eventually defeat the Philistines.
