"... Particularly notable, however, is Psalm 22:13, where the psalmist laments concerning his enemies who “open wide their mouth at me, as a ravening and a roaring lion” that arguably resembles most closely the language in 1 Peter 5:8 of the devil “as a roaring lion” (ὡς λέων ὠρυόμενος). Consequently, this psalm has frequently been seen as “the apparent source of Peter’s imagery,” with some such as Peter H. Davids more confidently asserting that “the image is surely drawn from Psalm 22:13,” though not all have been persuaded of this connection. Charles Bigg has suggested that 1 Peter 5:8 is a composite reference, drawing partly from the prowling lion in Psalm 22:13 and the prowling slanderer of Job. If so, the roaming of ὁ διάβολος in 1 Peter 5:8 (περιπατέω) would mirror the roaming of ὁ διάβολος in Job 1:7 (περιέρχομαι; compare διαπορεύομαι in 2:2) and in both texts God’s sovereignty would be upheld even when he permits trials from the devil for the testing his servants. Alternatively, Craig S. Keener identifies Ezekiel 22:25, 28 as “the passage that most likely provides some of the wording here” wherein the false prophets “were, as here, like a roaring lion devouring lives.” ..."
