James 2:13?

[NaphtaliPress]

Could the below be drawing on anything besides James 2:13? At least that seems to be the source.
"Judgment merciless to him that despises mercy." David Dickson, sermons on Lamentations.

 

[Ask Mr. Religion]

ASV rendering of James 2:13,
“For judgment will be merciless to one who has shown no mercy; but mercy triumphs over judgment.”

So, yes, it seems a nice fit.
