A primary word; a "lion" -- lion.
a. properly: Hebrews 11:33; 1 Peter 5:8; Revelation 4:7; Revelation 9:8, 17; Revelation 10:3; Revelation 13:2.
b. metaphorically ἐρρύσθην ἐκ στόματος λέοντος, I was rescued out of the most imminent peril of death, 2 Timothy 4:17 (the figure does not lie in the word lion alone, but in the whole phrase); equivalent to a brave and mighty hero: Revelation 5:5, where there is allusion to Genesis 49:9; cf. Nahum 2:13.
