Psalm 7:15-17

Amplified Bible

¹⁵ 
He has dug a pit and hollowed it out,
And has fallen into the [very] pit which he made [as a trap].
¹⁶ 
His mischief will return on his own head,
And his violence will come down on the top of his head [like loose dirt].

¹⁷ 
I will give thanks to the Lord according to His righteousness and justice,
And I will sing praise to the name of the Lord Most High.
