Be merciful, O Lord, to thy people Israel, whom thou hast redeemed,.... Out of Egyptian bondage, and claimed as his own; and therefore it is requested he would be favourable to them, and show them mercy, and not punish them for a sin they were entirely ignorant of, though done by some one among them, whom as yet they could not discover. The words seem to be the words of the elders continued, who having made a declaration of their innocence, humbly request mercy of God, not only for themselves, but for all the people of Israel; yet, both the Targums of Onkelos and Jonathan take them to be the words of the priests, and so does Jarchi, and the same is affirmed in the Misnah (z):

and lay not innocent blood unto thy people of Israel's charge; impute not the guilt of innocent blood to a people in general, when only a single person, and he unknown, is chargeable with it: or put it not "in the midst" of thy people; let it not be placed to the whole, because it cannot be found out whose it is, though it is certain it is one in the midst of them:

and the blood shall be forgiven them; that is, God will not impute it, and place it to their account, or lay it to their charge; but will graciously consider the beheading of the heifer as an expiation of it: it is said in the Misnah (a),"if the murderer is found before the heifer is beheaded, it goes forth and feeds among the herd; but if after it is beheaded, it is buried in the same place; and again, if the heifer is beheaded, and after that the murderer is found, he shall be slain;''so the Targums, and Jarchi on the next verse.

(z) Ut supra. (Sotah. c. 9. sect. 5.) (a) Hilchot Rotzeach, c. 9. sect. 7.

Be merciful, {c} O LORD, unto thy people Israel, whom thou hast redeemed, and lay not innocent blood unto thy people of Israel's charge. And the blood shall be forgiven them.

(c) This was the prayer, which the priests made in the audience of the people.

21:8 Forgiven - Though there was no mortal guilt in this people, yet there was a ceremonial uncleanness in the land, which was to be expiated and forgiven.

See Scofield Note: "Ex 14:30".

21:1-9 If a murderer could not be found out, great solemnity is provided for putting away the guilt from the land, as an expression of dread and detesting of that sin. The providence of God has often wonderfully brought to light these hidden works of darkness, and the sin of the guilty has often strangely found them out. The dread of murder should be deeply impressed upon every heart, and all should join in detecting and punishing those who are guilty. The elders were to profess that they had not been any way aiding or abetting the sin. The priests were to pray to God for the country and nation, that God would be merciful. We must empty that measure by our prayers, which others are filling by their sins. All would be taught by this solemnity, to use the utmost care and diligence to prevent, discover, and punish murder. We may all learn from hence to take heed of partaking in other men's sins. And we have fellowship with the unfruitful works of darkness, if we do not reprove them.
