Verse 12: (see Num. 14:45; Judg. 2:14) Therefore the children of Israel could not stand before their enemies, but turned their backs before their enemies, because (Deut. 7:26; Josh. 6:18) they were accursed: neither will I be with you any more, except ye destroy the accursed from among you.
[And he shall not be able to stand before his enemies] Again, לִפְנֵי/before in the place of מִלִּפְנֵי, from before (Masius). Question: Why are all punished because of one, Achan? This was answered previously, but I add, 1. that those thirty-six men suffered punishment, not for the sins of Achan, but for their own. 2. God is generally wont to exercise His judgments on account of those offenses that by contact might spread to all, of which sort are those of Kings, of the seditious, etc. Therefore, since here it was a sin against a law recently delivered, God willed to make an example, lest they should weaken all discipline at the beginnings of this critically important war by their impunity, although there were at that time either similar or more detestable sins in the people, which were not chastened (Masius).
[Because he was polluted by the accursed thing, כִּ֥י הָי֖וּ לְחֵ֑רֶם] They are (or, were) in anathema (Junius and Tremellius, Vatablus), that is, of the accursed thing (Junius); they are polluted by the accursed thing (Vatablus), unto anathema (Drusius, Piscator); because they were made anathema, that is, a thing devoted to God (Piscator). Thus, to be unto wife means to be for a wife, or, to be a wife actually (ל sometimes denotes the truth of a thing, sometimes only a similitude): I shall be for a God, that is, I shall be God; I shall be for a father, that is, I shall be a father; they shall be for one flesh, that is, as one flesh, that is, one body (Drusius).
Because they were accursed, as I warned and threatened them, Joshua 6:18, they have put themselves out of my protection and blessing, and therefore are liable to the same destruction which belongs to this accursed people.
[Who is guilty of this sin] Hebrew: חֵרֶם, the accursed thing; ἀνάθεμα/ anathema (Septuagint). Him that stole the accursed thing; who is liable to the anathema (Drusius). Both the things devoted to the anathema, and those that had drawn the contagion of the same crime, namely, the family and things of Achan (Malvenda out of Junius). Unless ye remove this sacrilege, with its author destroyed and devoted (certain interpreters in Malvenda).
 Hebrew: וְלֹ֙א יֻכְל֜וּ בְּנֵ֣י יִשְׂרָאֵ֗ל לָקוּם֙ לִפְנֵ֣י אֹיְבֵיהֶ֔ם עֹ֗רֶף יִפְנוּ֙ לִפְנֵ֣י אֹֽיְבֵיהֶ֔ם כִּ֥י הָי֖וּ לְחֵ֑רֶם לֹ֤א אוֹסִיף֙ לִֽהְי֣וֹת עִמָּכֶ֔ם אִם־לֹ֥א תַשְׁמִ֛ידוּ הַחֵ֖רֶם מִֽקִּרְבְּכֶֽם׃
 Hebrew: וְלֹ֙א יֻכְל֜וּ בְּנֵ֣י יִשְׂרָאֵ֗ל לָקוּם֙ לִפְנֵ֣י אֹיְבֵיהֶ֔ם .
 For example, Jeremiah 24:7: “And I will give them an heart to know me, that I am the Lord: and they shall be my people, and I will be their Godוְהָיוּ־לִ֣י לְעָ֔ם וְאָ֣נֹכִ֔י אֶהְיֶ֥ה) לָהֶ֖ם לֵאלֹהִ֑ים): for they shall return unto me with their whole heart.”
 For example, Genesis 17:4: “As for me, behold, my covenant is with thee, and thou shalt be a father (וְהָיִ֕יתָ לְאַ֖ב) of many nations.”
 For example, Genesis 2:24: “Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh (וְהָי֖וּ לְבָשָׂ֥ר אֶחָֽד׃).”
 Joshua 7:12b: “…neither will I be with you any more, except ye destroy the accursed from among you (הַחֵ֖רֶם מִֽקִּרְבְּכֶֽם׃).”
