Psalms 9:16

The LORD is known by the judgment which he executeth: the wicked is snared in the work of his own hands. Higgaion. Selah.

The Lord becomes known through the judgments He executes, revealing His character in the act of judging. His judgments make Him known precisely because He judges rightly, with justice that cannot be mistaken for arbitrariness or error. In that righteous judging, the wicked are snared in the work of their own hands, trapped by what they themselves have done. Their own deeds produce the consequences that catch them, so that their downfall is the fruit of their own actions.
