2. Mose 20:3

Thou shalt have no other gods before me - אלהים אחרים elohim acherim, no strange gods - none that thou art not acquainted with, none who has not given thee such proofs of his power and godhead as I have done in delivering thee from the Egyptians, dividing the Red Sea, bringing water out of the rock, quails into the desert, manna from heaven to feed thee, and the pillar of cloud to direct, enlighten, and shield thee. By these miracles God had rendered himself familiar to them, they were intimately acquainted with the operation of his hands; and therefore with great propriety he says, Thou shalt have no strange gods before me; על פני al panai, before or in the place of those manifestations which I have made of myself. This commandment prohibits every species of mental idolatry, and all inordinate attachment to earthly and sensible things. As God is the fountain of happiness, and no intelligent creature can be happy but through him, whoever seeks happiness in the creature is necessarily an idolater; as he puts the creature in the place of the Creator, expecting that from the gratification of his passions, in the use or abuse of earthly things, which is to be found in God alone. The very first commandment of the whole series is divinely calculated to prevent man's misery and promote his happiness, by taking him off from all false dependence, and leading him to God himself, the fountain of all good.

Thou shalt have no other gods before me--in My presence, beside, or except Me.

Thou shalt have no other gods before me. This is the first command, and is opposed to the polytheism of the Gentiles, the Egyptians, from whom Israel was just come, and whose gods some of them might have had a favourable opinion of and liking to, and had committed idolatry with; and the Canaanites, into whose land they were going; and to prevent their joining with them in the worship of other gods, this law was given, as well as to be of standing us to them in all generations; for there is but one only living and true God, the former and maker of all things, who only is to be had, owned, acknowledged, served, and worshipped as such; all others have only the name, and are not by nature gods; they are other gods than the true God is; they are not real, but fictitious deities; they are other or strange gods to the worshippers of them, that cry unto them, for they do not answer them, as Jarchi observes: and now for Israel, who knew the true God, who had appeared unto them, and made himself known to them by his name Jehovah, both by his word and works, whom he had espoused to himself as a choice virgin, to commit idolatry, which is spiritual adultery with other gods, with strange gods, that are no gods, and this before God, in the presence of him, who had took them by the hand when he brought them out of Egypt, and had been a husband to them, must be shocking impiety, monstrous ingratitude, and extremely displeasing to God, and resented by him; and is, as many observe, as if a woman should commit adultery in the presence of her husband, and so the phrase may denote the audaciousness of the action, as well as the wickedness of it; though, as Ben Melech from others observes, if it was done in secret it would be before the Lord, who is the omniscient God, and nothing can be hid…

The First Word. - "Let there not be to thee (thou shalt have no) other gods פּני על פּן," lit., beyond Me (על as in Gen 48:22; Psa 16:2), or in addition to Me (על as in Gen 31:50; Deu 19:9), equivalent to πλὴν ἐμοῦ (lxx), "by the side of Me" (Luther). "Before Me," coram me (Vulg., etc.), is incorrect; also against Me, in opposition to Me. (On פּני see Exo 33:14.) The singular יהיה does not require that we should regard Elohim as an abstract noun in the sense of Deity; and the plural אחרים would not suit this rendering (see Gen 1:14). The sentence is quite a general one, and not only prohibits polytheism and idolatry, the worship of idols in thought, word, and deed (cf. Deu 8:11, Deu 8:17, Deu 8:19), but also commands the fear, love, and worship of God the Lord (cf. Deu 6:5, Deu 6:13, Deu 6:17; Deu 10:12, Deu 10:20). Nearly all the commandments are couched in the negative form of prohibition, because they presuppose the existence of sin and evil desires in the human heart.

All things being prepared for the solemn promulgation of the divine law, we have, in this chapter, I. The ten commandments, as God himself spoke them upon mount Sinai (v. 1-17), as remarkable a portion of scripture as any in the Old Testament. II. The impressions made upon the people thereby (Exo 20:18-21). III. Some particular instructions which God gave privately to Moses, to be by him communicated to the people, relating to his worship (Exo 20:22, etc.).

20:3-17 The terms of the covenant specify the behavior the people were expected to manifest if they were to be in a covenant with God. Only the first four instructions (20:2-11) relate directly to God, while the remaining six (20:12-17) have to do with human-to-human relationships. A covenant with God stipulates how we are to treat each other because God is profoundly ethical, and he expects us to manifest his character in all our relationships. Other law codes in the ancient Near East did not incorporate such absolute prohibitions, probably because polytheism mitigated against absolute principles. In contrast, covenants with a king did include absolute prohibitions because a single king could demand whatever he wished of his subjects. Here the single king is the sole Creator of the universe, who truly has authority to state absolute principles, demands, and prohibitions. 20:3-11 The first four commandments relate to one’s relationship with God. Observing them would foster a correct understanding of God in contrast to the idolatrous notions of deity that the Israelites had encountered in Egypt and would yet encounter in Canaan. 20:3 Not recognizing any other god is the first step toward learning the truth that there are no other gods besides the Lord (see Deut 4:35; 6:4; Isa 43:10-11; 45:21-22).
