Revelation 4:8

Each of them six wings. See the like visions, Ezechiel i. 4; Isaias vi. 2. These signify their swiftness in executing God's just commands. --- Full of eyes: a symbol of knowledge and watchfulness. --- They rested not day and night. There is no night in heaven; but hereby is signified, that they praised God without intermission for all eternity, saying: Thou art worthy, O Lord, our[2] God, &c. (Witham) --- They repeat the word holy three times, probably in honour of the blessed Trinity. And the four and twenty elders prostrate before the throne, in token of their acknowledging all their happiness and pre-eminence to be his gift. (Walmesley)
