17Let not thine heart envy sinners: but be thou in the fear of the LORD all the day long. 18For surely there is an end; and thine expectation shall not be cut off. 19Hear thou, my son, and be wise, and guide thine heart in the way. 20Be not among winebibbers; among riotous eaters of flesh:21For the drunkard and the glutton shall come to poverty: and drowsiness shall clothe a man with rags. 22Hearken unto thy father that begat thee, and despise not thy mother when she is old. 23Buy the truth, and sell it not; also wisdom, and instruction, and understanding.
