'Sin Against' in the Bible

Now as for me, far be it from me that I should sin against the LORD by ceasing to pray for you. I'll also instruct you in the way that is good and right.

Then Saul said, "Disperse yourselves among the soldiers and say to them, "Let each man bring his ox and his sheep to me, and you are to slaughter them here and eat. But don't sin against the LORD by eating meat with the blood.'" So every soldier brought his ox with him that night, and they slaughtered them there.
