Targum zu Kohelet 4:16

There was no end to all the house of Israel, to all the righteous before whom he ruled; but they advised him in their wisdom to lighten their yoke, and he in his folly went and took counsel with the youth, and they in their folly, advised him to make heavier the yoke of his kingdom upon the people of the house of Israel, and he left the advice of the aged, and followed the advice of the latter; but these latter ones were afterwards confounded and displeased with him, and they caused him to flee, so that the ten tribes should separate from him ; and the wicked Jeroboam ruled over them ; I said this too is vanity for Rehoboam my son, and breaking of spirit to him.
