OBLIGATION
To keep the law is a great obligation and who observes the commandments sacrifices a peace offering. In works of charity one offers the fine flour, and when he gives alms he presents his sacrifice of praise. To refrain from evil pleases the Lord, and to avoid injustice is an atonement. Appear not before the Lord empty-handed, for all that you offer is fulfillment of the precepts. The just one's offering enriches the altar and rises as a sweet odor before the Most High. The just one's sacrifice is most pleasing, nor will it ever be forgotten....... Trust not in sacrifice of the fruits of extortion. For he is a God of justice who knows no favorites. Sir. 35:1-12
