Ver. 17. Learn to do well.] Turn over a new leaf, take out a new lesson. "Be thou instructed, O Jerusalem, lest God's soul depart from thee." Jer 6:8 Deliver thyself wholly up to his discipline; religion is the best learning - Philosophia sacra; to know Christ and him crucified is as much as St Paul cared for; Deum cognoscere et colere to know and honour God, is the whole duty of man; add this to the former. Negative goodness profiteth not.

What a good justicer and householder both he was, see Psalms 101:1,8

Judge the fatherless; plead for the widow.] These are God's own clients. Exo 22:22
