'Think' in the Bible

So her husband Elkanah said to her, "Do what you think best. Stay until you have weaned him. May the Lord fulfill his promise." So the woman stayed and nursed her son until she had weaned him.

Then he said to all Israel, "You will be on one side, and I and my son Jonathan will be on the other side." The army replied to Saul, "Do whatever you think is best."
