1 Peter 2:19

For this is thankworthy
Or "grace"; this is a fruit and effect of grace, an instance of it, in which it shows itself: the Syriac version adds, "with God"; and so it is read in one of Beza's copies, and in the Alexandrian copy, and some others; that is, this is grateful to God, and acceptable with him; as in ( 1 Peter 2:20 ) ,

if a man for conscience towards God;
or, "for a good conscience", as the Syriac version reads it; for acting according to his conscience, in matters of religion, in the things of God; "for the knowledge of God", as the Arabic version renders it; for the knowledge of God in Christ; for the Gospel of Christ, and a profession of it: or, "for God", as the Ethiopic version; for the cause of God and truth, and for the sake of things appertaining to God, and that make for his glory:

endure grief;
what occasions grief, as severe words, bitter reproaches, hard censures, and heavy blows; and that with patience, and without murmuring, and with resignation to the will of God:

suffering wrongfully;
there being no just cause for an ill look, word, or blow, to be given.
