Matthew Poole and continuators on Jeremiah 22:16

16 He judged the cause of the poor and needy , then it was well with him: was not this to know me? saith the LORD .

By himself in person for the Kings of Israel and Iudah, often sate personally to judge causes: or by setting such Judges as did it, administring justice impartially, particularly to such as in respect of their low condition were most exposed to the power of others, and doing thus he prospered.

This was for him truly to own and acknowledge me, they onely truly know God who obey him, and men vainly pretend to Piety, who are notoriously defective in duties of Justice and Charity.
