'Thanks' in the Bible

If I partake with thankfulness, why am I evil spoken of for that for which I give thanks?

and when he had given thanks, he brake it, and said, This is my body, which is for you: this do in remembrance of me.

Else if thou bless with the spirit, how shall he that filleth the place of the unlearned say the Amen at thy giving of thanks, seeing he knoweth not what thou sayest?

For thou verily givest thanks well, but the other is not edified.

but thanks be to God, who giveth us the victory through our Lord Jesus Christ.
