12 Make to yourself friends of the mammon of unrighteousness that they may receive you into everlasting habitations. Give your riches not to those who feed on pheasants but to those who have none but common bread to eat, such as stays hunger while it does not stimulate lust. Consider the poor and needy. Give to everyone that asks of you, but especially unto them who are of the household of faith. Clothe the naked, feed the hungry, visit the sick. Every time that you hold out your hand, think of Christ. See to it that you do not, when the Lord your God asks an alms of you, increase riches which are none of His.
