By swearing, and lying - Literally, "swearing or cursing" , "and lying, and killing, and stealing, and committing adultery!" The words in Hebrew are nouns of action. The Hebrew form is very vivid and solemn. It is far more forcible than if he had said, "They swear, lie, kill, and steal." It expresses that these sins were continual, that nothing else (so to speak) was going on; that it was all one scene of such sins, one course of them, and of nothing besides; as we say more familiarly, "It was all, swearing, lying, killing, stealing, committing adultery." It is as if the prophet, seeing with a sight above nature, a vision from God, saw, as in a picture, what was going on, all around, within and without, and summed up in this brief picture, all which he saw. This it was and nothing but this, which met his eyes, wherever he looked, whatever he heard, "swearing, lying, killing, stealing, committing adultery." The prophet had before said, that the ten tribes were utterly lacking in all truth, all love, all knowledge of God. But where there are none of these, "there," in all activity, will be the contrary vices. When the land or the soul is empty of the good, it will be full of the evil. "They break out," i. e., burst through all bounds, set to restrain them, as a river bursts its banks and overspreads all things or sweeps all before it. "And blood toucheth blood," literally, "bloods touch bloods" . The blood was poured so continuously and in such torrents, that it flowed on, until stream met stream and formed one wide inundation of blood.

By swearing, and lying - Where there is no truth there will be lies and perjury; for false swearing is brought in to confirm lying statements. And when there is no mercy, killing, slaying, and murders, will be frequent. And where there is no knowledge of God, no conviction of his omnipresence and omniscience, private offenses, such as stealing, adulteries, etc., will prevail. These, sooner or later, break out, become a flood, and carry all before them. Private stealing will assume the form of a public robbery, and adulteries become fashionable, especially among the higher orders; and suits of crim. con. render them more public, scandalous, and corrupting. By the examination of witnesses, and reading of infamous letters in a court of justice, people are taught the wiles and stratagems to be used to accomplish these ends, and prevent detection; and also how to avoid those circumstances which have led to the detection of others. Every report of such matters is an experimental lecture on successful debauchery.
Blood toucheth blood - Murders are not only frequent, but assassinations are mutual. Men go out to kill each other; as in our duels, the frenzy of cowards; and as there is no law regarded, and no justice in the land, the nearest akin slays the murderer. Even in our land, where duels are so frequent, if a man kill his antagonist, it is murder; and so generally brought in by an honest coroner and his jury. It is then brought into court; but who is hanged for it? The very murder is considered as an affair of honor, though it began in a dispute about a prostitute; and it is directed to be brought in manslaughter; and the murderer is slightly fined for having hurried his neighbor, perhaps once his friend, into the eternal world, with all his imperfections on his head! No wonder that a land mourns where these prevail; and that God should have a controversy with it. Such crimes as these are sufficient to bring God's curse upon any land. And how does God show his displeasure? See the following verse.

By swearing, and lying, and killing, and stealing, and committing adultery, they break out, and (b) blood toucheth blood.
(b) In every place appears a liberality to most wicked vices, so that one follows right after another.

By swearing, and lying,.... Which some join together, and make but one sin of it, false swearing, so Jarchi and Kimchi; but that swearing itself signifies, as the Targum interprets it; for it not only takes in all cursing and imprecations, profane oaths, and taking the name of God in vain, and swearing by the creatures, but may chiefly design perjury; which, though one kind of "lying", may be distinguished from it here; the latter intending "lying" in common, which the devil is the father of, mankind are incident unto, and which is abominable to God, whether in civil or in religious things: "and killing, and stealing and committing adultery"; murders, thefts, and adulteries, were very common with them; sins against the sixth, eighth, and seventh commandments:
they break out; through all the restraints of the laws of God and man, like an unruly horse that breaks his bridle and runs away; or like wild beasts, that break down the fences and enclosures about them, and break out, and get away; or like a torrent of water, that breaks down its dams and banks, and overflows the meadows and plains; such a flood and deluge of sin abounded in the nation. Some render it, "they thieve" (o); or act the part of thieves and robbers: and the Targum,
"they beget sons of their neighbours' wives;''
and so Abarbinel interprets it of breaking through the hedge of another man's wife; but these sins are observed before:
and blood toucheth blood; which some understand of sins in general, so called, because filthy and abominable; and of the addition and multiplication of them, there being as it were heaps of them, or rather a chain of them linked together. So the Targum,
"and they add sins to sins.''
Others interpret it of impure mixtures, of incestuous lusts, or marriages contrary to the ties of blood, and laws of consanguinity, Leviticus 18:6, or rather it is to be understood of the great effusion of blood, and frequency of murders; so that there was scarce any interval between them, but a continued series of them. Some think respect is had to the frequent slaughter of their kings; Zachariah the son of Jeroboam was slain by Shallum, when he had reigned but six months; and Shallum was slain by Menahem when he had reigned but one month; and this Menahem was a murderer of many, smote many places, and ripped up the women with child; Pekahiah his son was killed by Pekah the son of Remaliah, and he again by Hoshea, 2-Kings 15:8.
(o) "latrocinantur, vel latrones agunt", Schmidt.

they break out--bursting through every restraint.
blood toucheth blood--literally, "bloods." One act of bloodshed follows another without any interval between (see 2-Kings 15:8-16, 2-Kings 15:25; Micah 7:2).

"Swearing, and lying, and murdering, and stealing, and committing adultery; they break in, and blood reaches to blood." The enumeration of the prevailing sins and crimes commences with infin. absoll., to set forth the acts referred to as such with the greater emphasis. 'Alâh, to swear, in combination with kichēsh, signifies false swearing (= אלוה שׁוא in Hosea 10:4; compare the similar passage in Jeremiah 7:9); but we must not on that account take kichēsh as subordinate to 'âlâh, or connect them together, so as to form one idea. Swearing refers to the breach of the second commandment, stealing to that of the eighth; and the infinitives which follow enumerate the sins against the fifth, the seventh, and the sixth commandments. With pârâtsū the address passes into the finite tense (Luther follows the lxx and Vulg., and connects it with what precedes; but this is a mistake). The perfects, pârâtsū and nâgâ‛ū, are not preterites, but express a completed act, reaching from the past into the present. Pârats to tear, to break, signifies in this instance a violent breaking in upon others, for the purpose of robbery and murder, "grassari as פריצים, i.e., as murderers and robbers" (Hitzig), whereby one bloody deed immediately followed another (Ezekiel 18:10). Dâmı̄m: blood shed with violence, a bloody deed, a capital crime.

Break out - As waters that swell above all banks. Toucheth blood - Slaughters are multiplied; so that the end of one is the beginning of another.
