Solomon reminds his listeners that God is always on the side of the fatherless, the outcast and those who are vulnerable. This Proverb was a way of teaching the younger generation that the 'Defender of the weak' (Yahweh) will take up the case of the defenseless. It may seem that the poor can't afford lawyers fees, but their Advocate is none other than God himself.

“Defend the weak, protect both young and old, never desert your friends. Give justice to all, be fearless in battle and always ready to defend the right." - Brian Jacques
