'Experience' in the Bible

“Lord my God, You have now made Your servant king in my father David’s place. Yet I am just a youth with no experience in leadership.

A man of God approached and said to the king of Israel, “Thus says the Lord, ‘Because the Arameans have said, “The Lord is a god of the hills, but He is not a god of the valleys,” I will give this great army into your hand, and you shall know [by experience] that I am the Lord.’”
