Psalms 30:12
To the end that my glory may sing praise to thee, and not be silent. O LORD my God, I will give thanks unto thee for ever. To the end that my glory may sing praise to thee, and not be silent. O LORD my God, I will give thanks unto thee for ever.
God's deliverance in the verse turns mourning into gladness, and that reversal calls forth praise and thanks. The gladness is lasting, so the praise and thanks it awakens endure rather than fade. In response the speaker's glory sings praise to God and refuses to be silent. That song becomes unending thanksgiving, given to the Lord as God forever.
