Unto thousands - unto the thousandth generation. Yahweh's visitations of chastisement extend to the third and fourth generation, his visitations of mercy to the thousandth; that is, forever. That this is the true rendering seems to follow from Deuteronomy 7:9; Compare 2 Samuel 7:15-16.

And showing mercy unto thousands - Mark; even those who love God and keep his commandments merit nothing from him, and therefore the salvation and blessedness which these enjoy come from the mercy of God: Showing mercy, etc. What a disproportion between the works of justice and mercy! Justice works to the third or fourth, mercy to thousands of generations! The heathen had maxims like these. Theocritus also teaches that the children of the good shall be blessed because of their parents' piety, and that evil shall come upon the offspring of the wicked: -

Ευσεβεων παιδεσσι τα λωΐα, δυσσεβεων δ' ου.

Idyll. 26, v. 32.

Upon the children of the righteous fall

The choicest blessings; on the wicked, wo.

That love me, and keep my commandments - It was this that caused Christ to comprise the fulfillment of the whole law in love to God and man; see Clarke's note on Exodus 20:1. And as love is the grand principle of obedience, and the only incentive to it, so there can be no obedience without it. It would be more easy even in Egyptian bondage to make brick without straw, than to do the will of God unless his love be shed abroad in the heart of the Holy Spirit. Love, says the apostle, is the fulfilling of the law; Romans 13:10.

And showing mercy unto thousands of them that love me,.... And show their love by worshipping God, and him only, by serving him acceptably with reverence and godly fear, by a cheerful obedience to all his commands, by all religious exercises, both internal and external, as follows:

and keep my commandments; not only this, but all others; for keeping these from right principles, and with right views, is an instance and evidence of love to God, see John 14:15 and to such persons he shows mercy and kindness, performs acts of grace, and bestows on them blessings of goodness; and indeed it is owing to his own grace, mercy, and kindness to them, that they do love him, and from a principle of love observe his precepts; and this is shown to thousands, to multitudes, who are blessed with such grace as to love the Lord, and keep his commandments: though rather this is to be understood of a thousand generations, and not persons, and should have been supplied, as in the preceding verse, "unto a thousand generations", God being more abundant in showing mercy, and exercising grace and goodness, than he is rigorous in inflicting punishment.

And shewing mercy unto {e} thousands of them that love me, and keep my commandments.

(e) So ready is he rather to show mercy than to punish.

20:3-11 The first four of the ten commandments, commonly called the FIRST table, tell our duty to God. It was fit that those should be put first, because man had a Maker to love, before he had a neighbour to love. It cannot be expected that he should be true to his brother, who is false to his God. The first commandment concerns the object of worship, JEHOVAH, and him only. The worship of creatures is here forbidden. Whatever comes short of perfect love, gratitude, reverence, or worship, breaks this commandment. Whatsoever ye do, do all the glory of God. The second commandment refers to the worship we are to render to the Lord our God. It is forbidden to make any image or picture of the Deity, in any form, or for any purpose; or to worship any creature, image, or picture. But the spiritual import of this command extends much further. All kinds of superstition are here forbidden, and the using of mere human inventions in the worship of God. The third commandment concerns the manner of worship, that it be with all possible reverence and seriousness. All false oaths are forbidden. All light appealing to God, all profane cursing, is a horrid breach of this command. It matters not whether the word of God, or sacred things, all such-like things break this commandment, and there is no profit, honour, or pleasure in them. The Lord will not hold him guiltless that taketh his name in vain. The form of the fourth commandment, Remember, shows that it was not now first given, but was known by the people before. One day in seven is to be kept holy. Six days are allotted to worldly business, but not so as to neglect the service of God, and the care of our souls. On those days we must do all our work, and leave none to be done on the sabbath day. Christ allowed works of necessity, charity, and piety; for the sabbath was made for man, and not man for the sabbath, Mr 2:27; but all works of luxury, vanity, or self-indulgence in any form, are forbidden. Trading, paying wages, settling accounts, writing letters of business, worldly studies, trifling visits, journeys, or light conversation, are not keeping this day holy to the Lord. Sloth and indolence may be a carnal, but not a holy rest. The sabbath of the Lord should be a day of rest from worldly labour, and a rest in the service of God. The advantages from the due keeping of this holy day, were it only to the health and happiness of mankind, with the time it affords for taking care of the soul, show the excellency of this commandment. The day is blessed; men are blessed by it, and in it. The blessing and direction to keep holy are not limited to the seventh day, but are spoken of the sabbath day.
