Verse 13: Remember (Num. 32:17-33; Josh. 22:2-4) the word which Moses the servant of the LORD commanded you, saying, The LORD your God hath given you rest, and hath given you this land.
[Remember, זָכוֹר] To remember, that is, it behooves you to remember (Lapide). The infinitive mood is in the place of the imperative (Masius, Malvenda, Drusius). Or, Remember, O triple Tribe. It is an enallage, either of tense, or number (Lapide). Singular in the place of the plural (Vatablus). Remember ye (the Chaldean in Vatablus).
Remember his charge to you, and your promise to him, which they were obliged to keep; and Joshua was to see that they did so.
[He hath given rest] In the beginning, He commemorates the most agreeable things, whereby He gains for Himself their hearts. And, when it is come to hard things, But ye shall pass before, etc., He flies across so quickly that He appears with one word both to wound and to heal their mind. With such skill He weaves the admonition. Quiet, that is, a place of quiet, and that altogether safe (Junius). He gave to you quiet settlements (Vatablus).
Rest, that is, a place of rest, as that word signifies: see on Genesis 49:15.
 Hebrew: זָכוֹר֙ אֶת־הַדָּבָ֔ר אֲשֶׁ֙ר צִוָּ֥ה אֶתְכֶ֛ם מֹשֶׁ֥ה עֶֽבֶד־יְהוָ֖ה לֵאמֹ֑ר יְהוָ֤ה אֱלֹהֵיכֶם֙ מֵנִ֣יחַ לָכֶ֔ם וְנָתַ֥ן לָכֶ֖ם אֶת־הָאָ֥רֶץ הַזֹּֽאת׃
 זָכוֹר is formally infinitive.
 That is, the use of one grammatical form in the place of another.
 See verse 14.
