'Searching' in the Bible

Now Barak was chasing Sisera. Jael went out to welcome him. She said to him, "Come here and I will show you the man you are searching for." He went with her into the tent, and there he saw Sisera sprawled out dead with the tent peg in his temple.

Issachar's leaders were with Deborah, the men of Issachar supported Barak; into the valley they were sent under Barak's command. Among the clans of Reuben there was intense heart searching.

Why do you remain among the sheepfolds, listening to the shepherds playing their pipes for their flocks? As for the clans of Reuben -- there was intense searching of heart.
