'Pray' in the Bible

For thou, O my God, hast told thy servant that thou wilt build him an house: therefore thy servant hath found in his heart to pray before thee.

And David said unto God, Is it not I that commanded the people to be numbered? even I it is that have sinned and done evil indeed; but as for these sheep, what have they done? let thine hand, I pray thee, O LORD my God, be on me, and on my father's house; but not on thy people, that they should be plagued.
