'Learned' in the Bible

When [the] Philistines heard the noise of the shouting, they said, "What [is] the noise of this loud shouting in the camp of the Hebrews?" Then they learned that the ark of Yahweh had come into the camp.

When David learned that Saul [was] plotting evil against him, he said to Abiathar the priest, "Bring the ephod here."

David sent spies, and he learned that Saul had come {for certain}.
