Charles H. Spurgeon on Psalms 112:9

For ever. The Hebrew phrase in this text is not Mlwel, in seculum, which is sometimes used of a limited eternity, but del, in eternum, which seems more expressive of an endless duration, and is the very same phrase whereby the duration of God's righteousness is expressed in the foregoing psalm at the third verse. —William Berriman, 1688-1749.

Verses 9-10. These words are an enlargement of the character, begun at the first verse, of the blessed man that feareth the Lord, that delighteth greatly in his commandments. The author closes that character with an amiable description of his charity, and so leaves on our minds a strong impression, that benevolence of heart when displayed in the benefaction of the hand is the surest mark and fairest accomplishment of a moral and religious mind; which, whether it rewards the worthy, or relieves the unworthy object, is the noblest imitation of the dealings of God with mankind. For he rewardeth the good if any can be called so but himself, (though the name good is but God spread out). He beareth even with the wicked and stretcheth out his hand to save even them. —Michael Cox.
