'Thank offering' in the Bible

the voice of joy and the voice of gladness, the voice of the bridegroom and the voice of the bride, the voice of those who say,“Give thanks to the Lord of hosts,For the Lord is good,For His lovingkindness is everlasting”;and of those who bring a thank offering into the house of the Lord. For I will restore the fortunes of the land as they were at first,’ says the Lord.

“Offer a thank offering also from that which is leavened,And proclaim freewill offerings, make them known.For so you love to do, you sons of Israel,”Declares the Lord God.
