Adam Clarke on Proverbs 11:25

The liberal soul shall be made fat - He who gives to the distressed, in the true spirit of charity, shall get a hundred fold from God's mercy. How wonderful is the Lord! He gives the property, gives the heart to use it aright, and recompenses the man for the deed though all the fruit was found from himself!

He that watereth - A man who distributes in the right spirit gets more good himself than the poor man does who receives the bounty. Thus it is more blessed to give than to receive.
