Revelation 4:7

It is observed concerning these four living creatures, (for so they were, not beasts in a strict sense, as it is opposed to flying things, for the fourth was a fowl):

1. That they were the same mentioned in Ezekiel's vision, Ezekiel 1:10; only each one there is said to have had the four faces of these creatures, here each one had a single face proper to it.

2. That these were the four creatures whose portraitures were in the four ensigns of the Israelites as they were marshalled into four companies, allotting the men of three tribes to each company. Judah's standard had a lion in its colours, according to Jacob's prophecy of that tribe, Genesis 49:9, Ephraim had an ox, Reuben had a man, Dan an eagle. This the learned Mede proves from the Rabbins, who, though fabulous enough, yet in such a thing may be credited. It is also thought they answered the four cherubims in the temple. Question. But what is signified by these four living creatures? Solution. Some say the four evangelists; others, four apostles, &c. But certainly they judge best who say, that by them is signified the various gifts with which God blesseth his ministers, giving to some more courage and fortitude, that they are like lions; to others more mildness and meekness, that they are like oxen or calves; others have more wisdom and prudence, which most adorn a man; others a more piercing insight into the mysteries of God's kingdom, rendering them like eagles.
