Psalm 50

Herein Yahweh chides his people that the acceptable sacrifice cannot just be surface piety, but must include genuine ethics, real reverence and praise of God: "Offer to God praise as your sacrifice and fulfill your vows to the Most High; Then call upon me in times of distress; I will rescue you, and you shall glorify me." Psalm 50, 14-15

Be moral, praise God by glorifying De with sincere sacrifice, and then your offering will well received: Do evil and abandone God and you will reap the whirlwind: "Consider this, you who forget God, lest I rend you and there be no one to rescue you. He that offers praise as a sacrifice glorifies me; and to him that goes the right way I will show the salvation of God." Psalm 50, 22-23
