Ecclesiastes 3:18; Ecclesiastes 7:14; Ecclesiastes 8:2

18 I said in mine heart concerning the estate of the sons of men, that God might manifest them, and that they might see that they themselves are beasts.

14 In the day of prosperity be joyful, but in the day of adversity consider: God also hath set the one over against the other, to the end that man should find nothing after him.

2 I counsel thee to keep the king's commandment, and that in regard of the oath of God.
