Behold, the ark of the covenant of the Lord of all the earth,.... Some both Jewish and Christian interpreters, because there is a distinguishing accent on the word "covenant", read the words "the ark of the covenant, even the Lord of all the earth"; so in some copies of our English Bible, as if the ark was called the Lord of all the earth, because of his presence and dwelling there; but, as Kimchi observes, either the word "ark" is wanting, or the word "covenant", and may be supplied either thus,"the ark of the covenant, the ark (I say) of the Lord of all the earth;''or thus,"the ark of the covenant, which is the covenant of the Lord of all the earth:''the true meaning is what Abarbinel gives,"the ark of the covenant of the Lord, who is the Lord of the whole earth;''the Maker and possessor of the whole earth, the whole terraqueous globe; and can do what he pleases in the earth, or in the water; and can control the powers of nature, and do what is beyond them, things miraculous and astonishing:

passeth before you into Jordan; not only unto it, but into it, into the river itself; and, by the power of him whose presence was with it, the waters of Jordan were to be divided, to give them a passage through it as on dry land, and so it came to pass.

After this inspiriting promise, Joshua informed the people what the Lord intended to do first: "Behold, the ark of the covenant of the Lord of the whole earth will go before you into Jordan." כּל־הארץ 'adown is a genitive dependent upon הברית ארון, the strict subordination of the construct state being loosened in this case by the article before the nomen regens. The punctuators have therefore separated it from the latter by sakeph-katon, without thereby explaining it as in opposition or giving any support to the mistaken exposition of Buxtorff and Drusius, that "the ark of the covenant is called the ruler of the whole earth." The description of Jehovah as "Lord of the whole earth," which is repeated in Joshua 3:13, is very appropriately chosen for the purpose of strengthening confidence in the omnipotence of the Lord. This epithet "exalted the government of God over all the elements of the world, that the Israelites might have no doubt that as seas and rivers are under His control, the waters, although liquid by nature, would become stable at His nod" (Calvin). The expression, "passeth over before you into Jordan," is more precisely explained in the course of the narrative: the ark of the covenant went (was carried) before the people into the river, and then stood still, as the bulwark of the people, till the passage was completed; so that the word "before" indicates the protection which it would afford.

Behold, the ark of the covenant of the LORD of all the earth passeth over before you into Jordan.

3:7-13 The waters of Jordan shall be cut off. This must be done in such a way as never was done, but in the dividing of the Red sea. That miracle is here repeated; God has the same power to finish the salvation of his people, as to begin it; the WORD of the Lord was as truly with Joshua as with Moses. God's appearances for his people ought to encourage faith and hope. God's work is perfect, he will keep his people. Jordan's flood cannot keep out Israel, Canaan's force cannot turn them out again.
