Passage Isaiah 5:26
Under the heading of qualities that do not befit God, the first is that he whistles. Isaiah 5:26 has him whistle for a nation from the ends of the earth, Zechariah 10:8 has him whistle for his people to gather them in, and Isaiah 7:18 uses the same image. The argument finds the picture too homely for the Almighty.
He will raise a signal for nations far away, and whistle for them from the ends of the earth; and behold, quickly, speedily they come!
Isaiah 5:26
“I will whistle for them and gather them in, for I have redeemed them, and they shall be as many as they were before.
Zechariah 10:8
