Sirach 34:18

18 He that sacrificeth of a thing wrongfully gotten, his offering is ridiculous; and the gifts of unjust men are not accepted.

Sirach 34:18 In-Context

16 For the eyes of the Lord are upon them that love him, he is their mighty protection and strong stay, a defence from heat, and a cover from the sun at noon, a preservation from stumbling, and an help from falling.
17 He raiseth up the soul, and lighteneth the eyes: he giveth health, life, and blessing.
18 He that sacrificeth of a thing wrongfully gotten, his offering is ridiculous; and the gifts of unjust men are not accepted.
19 The most High is not pleased with the offerings of the wicked; neither is he pacified for sin by the multitude of sacrifices.
20 Whoso bringeth an offering of the goods of the poor doeth as one that killeth the son before his father's eyes.
