Revelation 4:7
And the first being was like a lion, the second one was like a calf, the third one had the face of a man and the fourth one was like a flying eagle.
1 Corinthians 9:9-10
For it is written in the law of Moses [Deut. 25:4], "You should not put a muzzle on an ox while it tramples over the grain." Is it the oxen that God is concerned about?
1 Corinthians 14:20
Brothers, do not be children in the way you think, but be babies in wrongdoing; yet be mature in your thinking.
Revelation 4:6
And there was an ocean, as crystal-clear as glass, in front of the throne. And at the center, surrounding the throne were four living beings, covered with eyes in the front and back of them. [Note: In view of Isa. 6:1-3 and especially Eze. 10:20ff, these "living beings" appear to be some special order of heavenly beings who inhabit the presence of God].
