Verse 10: And Joshua said, Hereby ye shall know that (Deut. 5:26; 1 Sam. 17:26; 2 Kings 19:4; Hos. 1:10; Matt. 16:16; 1 Thess. 1:9) the living God is among you, and that he will without fail (Ex. 33:2; Deut. 7:1; Ps. 44:2) drive out from before you the Canaanites, and the Hittites, and the Hivites, and the Perizzites, and the Girgashites, and the Amorites, and the Jebusites.
[In this ye shall know] Namely, in the miracle of passing through Jordan on dry ground (Malvenda, Junius). This admonition was not superfluous for shaking off that slowness which is always in the minds of men to evaluate the Divine goodness according to truth; and lest in such a crown rumors should spread that they are crossing Jordan, and are attacking an incredibly powerful nation surrounded on all sides by the sea, mountains, and rivers, whence it would be evident that there would be no way of escape to those once defeated, and that it would be nothing other than to consign themselves to the power of the enemy (Masius). Ye shall know in experience, what hitherto ye hold in faith. Or, ye shall know is able to be taken of an increase in faith (Masius).
Hereby ye shall know, to wit, by experience and sensible evidence.
[The Lord, etc., אֵ֥ל חַ֖י] A most suitable epithet. אֵל/El, strong, or omnipotent. But victory is wont to be obtained by strength. חַי/living, who lives, active, vigorous. This signifies God’s vigorous industry and active providence and care, whereby He brings help to His own in a timely manner. For life (as Aristotle witnesses) is action, and is recognized from motion; of what things no action or motion appears, those things are reckoned to be dead or at least languid (Masius). Thus he distinguishes God from idols, which are without life, and therefore of no ability to accomplish wonderful things; while the life of God is able to be discerned by miracles (Bonfrerius). Living, invigorating all things, He shall carry you through Jordan alive (Lapide).
The living God; not a dull, dead, senseless, and unactive god, such as the gods of the nations are; but a God of life, and power, and activity, to watch over you, and work for you. Is among you; is present with you to strengthen and help you, as the phrase signifies, Exodus 17:7; Deuteronomy 31:17; Joshua 22:31.
[He will destroy in your sight] They note that יָרַשׁ, if מִפְּנֵי, from the face of, is subjoined to it, signifies to drive out of possession; otherwise, to possess (Masius).
[The Canaanite, etc.] He enumerates seven. But elsewhere ten, Genesis 15:19-21. Responses: 1. There God includes places toward Euphrates; here only places that are just beyond Lebo Hamath. See what things are on Joshua 1:4. 2. Those nations are signified sometimes with more, sometimes with fewer, names (Masius). 3. In Joshua, the principal and greater nations are enumerated; in Genesis, three minor nations are added (Malvenda). [See the things brought together by us on Genesis 15:18.]
 Hebrew: וַיֹּ֣אמֶר יְהוֹשֻׁ֔עַ בְּזֹאת֙ תֵּֽדְע֔וּן כִּ֛י אֵ֥ל חַ֖י בְּקִרְבְּכֶ֑ם וְהוֹרֵ֣שׁ יוֹרִ֣ישׁ מִ֠פְּנֵיכֶם אֶת־הַכְּנַעֲנִ֙י וְאֶת־הַחִתִּ֜י וְאֶת־הַחִוִּ֗י וְאֶת־הַפְּרִזִּי֙ וְאֶת־הַגִּרְגָּשִׁ֔י וְהָאֱמֹרִ֖י וְהַיְבוּסִֽי׃
 Hebrew: וְהוֹרֵ֣שׁ יוֹרִ֣ישׁ מִ֠פְּנֵיכֶם.
 לְבֹא חֲמָת, that is, the entrance of Hamath. Hamath itself is one hundred and sixty-seven miles north of the Sea of Galilee.
