The case of murder of a free man and of a bondman. See Exodus 21:20 note. The law was afterward expressly declared to relate also to foreigners, Leviticus 24:17, Leviticus 24:21-22; compare the marginal references.

He that smiteth a man, so that he die,.... The Targum of Jonathan is, that smites a man or daughter of Israel with the sword; but there is no need to restrain the words either to persons of any certain nation, nor to any instrument with which a person may be smitten as to die: but any human person, man, woman, or child, of whatsoever nation, and they smitten with anything whatever, that issues in their death:

shall surely be put to death; by the order of the civil magistrate, and by the hand of such as shall be appointed by him; for this is the original law of God, Genesis 9:6.

Still higher than personal liberty, however, is life itself, the right of existence and personality; and the infliction of injury upon this was not only prohibited, but to be followed by punishment corresponding to the crime. The principle of retribution, jus talionis, which is the only one that embodies the idea of justice, lies at the foundation of these threats.

Exodus 21:12-13

A death-blow was to be punished with death (cf. Genesis 9:6; Leviticus 24:17). "He that smiteth a man and (so that) he die (whether on the spot or directly afterwards did not matter), he shall be put to death." This general rule is still further defined by a distinction being drawn between accidental and intentional killing. "But whoever has not lain in wait (for another's life), and God has caused it to come to his hand" (to kill the other); i.e., not only if he did not intend to kill him, but did not even cherish the intention of smiting him, or of doing him harm from hatred and enmity (Numbers 35:16-23; Deuteronomy 19:4-5), and therefore did so quite unawares, according to a dispensation of God, which is generally called an accident because it is above our comprehension. For such a man God would appoint places of refuge, where he should be protected against the avenger of blood. (On this point, see Numbers 35:9.).

He that smiteth a man, so that he die, shall be surely put to death.

21:12-21 God, who by his providence gives and maintains life, by his law protects it. A wilful murderer shall be taken even from God's altar. But God provided cities of refuge to protect those whose unhappiness it was, and not their fault, to cause the death of another; for such as by accident, when a man is doing a lawful act, without intent of hurt, happens to kill another. Let children hear the sentence of God's word upon the ungrateful and disobedient; and remember that God will certainly requite it, if they have ever cursed their parents, even in their hearts, or have lifted up their hands against them, except they repent, and flee for refuge to the Saviour. And let parents hence learn to be very careful in training up their children, setting them a good example, especially in the government of their passions, and in praying for them; taking heed not to provoke them to wrath. Through poverty the Israelites sometimes sold themselves or their children; magistrates sold some persons for their crimes, and creditors were in some cases allowed to sell their debtors who could not pay. But man-stealing, the object of which is to force another into slavery, is ranked in the New Testament with the greatest crimes. Care is here taken, that satisfaction be made for hurt done to a person, though death do not follow. The gospel teaches masters to forbear, and to moderate threatenings, Eph 6:9, considering with Job, What shall I do, when God riseth up? Job 31:13,14.
