'Gah gah' in the Bible

For [it is] blah-blah upon blah-blah, blah-blah upon blah-blah, gah-gah upon gah-gah, gah-gah upon gah-gah, a little here, a little there.

And to them the word of Yahweh will be blah-blah upon blah-blah blah-blah upon blah-blah gah-gah upon gah-gah gah-gah upon gah-gah, a little here, a little there, so that they may go and stumble backward and be broken and ensnared and captured.
