fat of lambs

Psalms 37:16 A little that a righteous man hath is better than the riches of many wicked. 17 For the arms of the wicked shall be broken: but the Lord upholdeth the righteous. 18 The Lord knoweth the days of the upright: and their inheritance shall be for ever. 19 They shall not be ashamed in the evil time: and in the days of famine they shall be satisfied. 20 But the wicked shall perish, and the enemies of the Lord shall be as the fat of lambs: they shall consume; into smoke shall they consume away.
