Matthew Poole and continuators on Joshua 22:10

10 ¶ And when they came unto the borders of Jordan, that are in the land of Canaan, the children of Reuben, and the children of Gad, and the half tribe of Manasseh, built there an altar by Jordan, a great altar to see to.

Or, then, as this Particle is elsewhere used; and so Learned Interpreters understand it, Psal. 14. 5. and 36. 12. Eccles. 3. 17. Hos. 2. 15. And in the Latin Tongue Adverbs of Place are sometimes put for Adverbs of Time: So I take it here. First, Because this best answers to the when in the beginning of the Verse. Secondly, This seems to me to clear a great difficulty as to the place where this Altar was built, which though according to our Translation it seems and is generally thought by Interpreters to have been in the Land of Canaan; yet if things be more narrowly examined, it may be thought to have been on the other side Iordan in Gilead; and that both, First, from v. 11. where it is said to have been built over against, or, in the sight of the land of Canaan, therefore not in it. And Secondly, From the reason they give for the building of this Altar, for fear lest the Israelites within Iordan, and in Canaan, should say unto their Children dwelling beyond Iordan, The Lord hath made Iordan a border between us and you, &c. Which jealousie would have been much confirmed by building the Altar in Canaan, but would be satisfied and confuted by having on the other side of Iordan, and in their own Land, a pattern of that Altar at which God was served in the Land of Canaan, as a Witness that they owned the same God, and the same way of Worship with their Brethren that lived in Canaan. But whether the Hebrew Particle be rendred then or there, it is not to be taken too strictly; if then, the meaning is not, that they did this as soon as ever they came to the borders of Iordan, that are in the land of Canaan; but about that time when they came to them, they thought and designed it, and as soon as ever they were got over Iordan, which was in a very little time, they effected and perfected it: if it be rendred there, it is not to be limited to the very same spot of ground mentioned before, as if it was built at that border of Iordan that was in the Land of Canaan; but to be a little more largely understood; to be built at one or other of the borders of Iordan; or in general, by Iordan: which is here purposely added, for the Explication of the Word there, and to prevent the restraint of it to the border of Iordan, within Canaan.
