פועל טוב יקראנו בדרכיו ובעת מוטו ימצא משען

Whoever does a good deed, it will find him along the way; at the time he falls, he will find support.
This proverb is not quite equivalent to “one good turn deserves another,” which is a warning against ingratitude. Nor is it quite the same as “Do unto others as you would have them do to you,” which is a warning against being nasty toward others. This proverb seems rather an encouragement to do good with the promise that when you need help it will be there in return. I can only vaguely recall some TV commercial and a country and western song that both based on this idea. Most of the time, however, this sort of think is explained in terms of karma or law of attraction. No doubt Sirach thought instead in terms of God’s justice: everyone receives their “come-uppens,” and for the sages this was generally, and somewhat idealistically, thought to happen in this life.
