Psalms 15:5

He that putteth not out his money to usury - The word “usury” formerly denoted legal interest, or a premium for the use of money. In this sense the word is no longer used in our language, but it always now denotes unlawful interest; “a premium or compensation paid, or stipulated to be paid, for the use of money borrowed or retained, beyond the rate of interest established by law.” “Webster.” The Hebrew word used here - נשׁך neshek - means “interest,” that is, a premium or compensation for the use of money in any manner, or to any extent. The reference is to the law of the Hebrews, which forbade such a loaning of money to the poor, and especially to poor Israelites, Exodus 22:25; Leviticus 25:35. Although this was forbidden in respect to the Israelites, yet the lending of money on interest, or “usury” in a lawful sense, was allowed toward “strangers,” or toward the people of other nations.

See Deuteronomy 23:19. The ground of the distinction was, that the Hebrews were regarded as a nation of brethren; that, as such, they should be willing to accommodate and aid each other; that they should not do anything that could be regarded as unbrotherly. In respect to other people it was allowed, not because it was proper to take advantage of their wants, and to oppress them, but because this special reason did not exist in regard to them. That might be improper “in a family,” among brothers and sisters, which would be entirely proper toward those who did not sustain this special relation; and we may conceive of cases - such cases in fact often occur - when it would be unkind in the highest degree to exact interest of a brother, or an intimate friend, while it is perfectly proper to receive the ordinary allowance for the use of money in our business transactions (that is, the ordinary rate of interest) of those who do not sustain to us this special relation.

The fact that it was allowed to the Hebrews to take interest of the people of other nations, shows that there was nothing morally wrong in the thing itself; and, in fact, there can be no reason why a man, to whom it is an accommodation, should not pay for the use of money as well as for the use of any other property. The thing forbidden here, therefore, is not the taking of interest in any case, but the taking of interest in such a way as would be oppressive and hard - as of a Hebrew demanding it from his poor and needy brother; and, by consequence, it would forbid the exacting of unusual and unlawful rates of interest, or taking advantage of the necessities of others - by evading the provisions of law, and making their circumstances an occasion of extortion. In one word, the thing forbidden is a harsh, grasping, griping disposition; a disposition to take advantage of the embarrassments of others to increase our own gains. Kindness, and an accommodating spirit in business transactions, are as much demanded now by the principles of religion as they were when this psalm was written, or as they were under the law which forbade the taking of interest from a poor and needy brother.

Nor taketh reward against the innocent - Who does not take a bribe; that is, does not accept a pecuniary consideration, or any other consideration, to induce him to decide a cause against justice. He is not, in any way, to allow any such considerations to influence him, or to sway his judgment. The taking of bribes is often expressly forbidden in the Scriptures. See Exodus 23:8; Deuteronomy 16:19; Deuteronomy 27:25; Proverbs 17:23.

He that doeth these things shall never be moved - That is, in answer to the question in Psalms 15:1, he shall be permitted to “abide in the tabernacle” of God, and to “dwell in his holy hill.” He shall have a solid foundation of hope; he is a friend of God, and shall enjoy his favor forever. In other words, these things constitute true religion; and he who has such a character will obtain eternal life. His foundation is sure; he will be safe in all the storms of life, and safe when the cold waves of death beat around him. Compare Matthew 7:24.
