Daniel 4:24-26

The king’s condition, whatever it was, would continue for seven periods of time (cf. Daniel 4:16) until the king had learned that the Most High is sovereign. Then Nebuchadnezzar would receive back both his senses and his throne. "Heaven ruling" (Daniel 4:26) is a figure of speech (metonymy) for God ruling, since God lives in heaven. The Jews often substituted "heaven" for God’s name out of respect for Him. This is most obvious in Matthew’s Gospel, which was written primarily for Jews, in which "the kingdom of heaven" usually replaces the more common "kingdom of God" in the other Gospels. However, this is the only place in the Old Testament where the substitution of "heaven" for "God" occurs.
