New Defender's Study Bible Notes
1:9 Hebrew. The name “Hebrew” could actually apply to any of the descendants of Eber (Genesis 10:25; 11:16-19). Perhaps this was the sense in which Jonah expected this motley group to understand it. The term actually appears only fourteen times (this being the last) in the Old Testament.
1:9 God of heaven. Unlike the pagan polytheists he was traveling with, Jonah was a creationist, and his God was the only true God. His God had created the universe, including all the false gods (actually fallen angels and demons now in the Satanic hosts) worshiped by the pagan world.
