A.T. Robertson Commentary 1 Peter 4:19

"Wherefore let them also that suffer according to the will of God commit their souls in well-doing unto a faithful Creator." — 1 Peter 4:19 (ASV)

Wherefore (ωστε). Picking up the thread of consolation again (Bigg).

Commit their souls (παρατιθεσθωσαν τας ψυχας). Present (continuous) middle imperative third plural of παρατιθημ, old word, a banking figure, to deposit, as in 1 Timothy 1:18; 2 Timothy 2:2, the word used by Jesus as he died (Luke 23:46).

In well-doing (εν αγαθοποιια). Late and rare word, only here in N.T., from αγαθοποιεω (1 Peter 2:15,20).
