The generic word; human like ourselves, this thought being emphasized by the succeeding epithet of like passions. See the same expression, Act 14:15.
Of like passions (ὁμοιοπαθὴς)
Only here and Act 14:15. There is some danger of a misunderstanding of this rendering, from the limited and generally bad sense in which the word passions is popularly used. The meaning is rather of like nature and constitution. Rev. puts nature in margin, which would be better in the text.
He prayed fervently (προσευχῇ προσηύξατο)
Lit., he prayed with prayer. See a similar mode of expression, Genesis 2:17 (Sept.), ye shall surely die (θανάτῳ ἀποθανεῖσθε); lit., ye shall die with death. Compare Luk 22:15; Joh 3:29; Act 4:17. The addition of the cognate noun gives intenseness to the verb.
Hide - sins
A familiar Hebrew phrase. See Psa 32:1; Psa 85:2; Pro 10:12.
