'Learned' in the Bible

When the Philistines learned that David had been anointed king over all of Israel, all of the Philistines invaded to look for David. David heard about it and went out to fight them.

When King Tou of Hamath learned that David had conquered King Hadadezer of Zobah's entire army,

When David learned this, he mustered all of Israel, crossed the Jordan, approached the Arameans, and drew up his forces against them. After David had assembled in battle array against the Arameans, the Arameans attacked him.
