Sirach 3:31

31 And he that requiteth good turns is mindful of that which may come hereafter; and when he falleth, he shall find a stay.

Sirach 3:31 In-Context

29 The heart of the prudent will understand a parable; and an attentive ear is the desire of a wise man.
30 Water will quench a flaming fire; and alms maketh an atonement for sins.
31 And he that requiteth good turns is mindful of that which may come hereafter; and when he falleth, he shall find a stay.
