'Thank offering' in the Bible

If he offer to give thanks, he shall bring unto his thank offering: sweet cakes mingled with oil and sweet wafers anointed with oil, and cakes mingled with oil of fine flour fried,

and he shall bring his offering upon cakes made of leavened bread unto the thank offering of his peace offerings,

And the flesh of the thank offering of his peace offerings shall be eaten the same day that it is offered, and there shall none of it be laid up until the morning.

When ye will offer a thank offering unto the LORD, ye shall so offer it that ye may be accepted.

Ye made a thank offering of leaven, ye promised free will offerings, and proclaimed them. Such lust had ye, O ye children of Israel,' sayeth the LORD God.
