July 8 20171 Samuel 18:5, 14-165 And David went out wherever Saul sent him, and behaved himself wisely: and Saul set him over the men of war, and he was accepted in the sight of all the people, and also in the sight of Saul's servants.14 And David behaved himself wisely in all his ways; and the LORD was with him.15 Therefore when Saul saw that he behaved himself very wisely, he was afraid of him.16 But all Israel and Judah loved David, because he went out and came in before them.

Ecclesiastes 10:10 If the iron is blunt, and he does not sharpen the edge, then must he use more strength: but wisdom helps one to succeed.
