Verse 14: (Josh. 16:4) And the children of Joseph spake unto Joshua, saying, Why hast thou given me but (Gen. 48:22) one lot and one portion to inherit, seeing I am (Gen. 48:19; Num. 26:34, 37) a great people, forasmuch as the LORD hath blessed me hitherto?
[And the children of Joseph spoke] Question 1: Who then are these? Response 1: the Manassites (Munster, Vatablus, Hebrews in Masius). For these were greatly increased after the exodus out of Egypt (Munster). Compare Numbers 2:21, etc., with Numbers 26:34, etc. (Bonfrerius). And, that the movers of this inquiry were the Manassites, I do not deny: for no Tribe was encumbered with more difficulties, and none had more cities in the power of the Canaanites, than Manasseh: And that, as the Lord hath blessed me, appears to have regard to the Manassites, who were greatly increased in numbers, while the Ephraimites were diminished (Masius). Response 2: the Manassites and Ephraimites (Junius, Masius, Lapide, Bonfrerius); as it is apparent from verses 15-17 (Junius). Question 2: When did they say this? Response: After the rest of Canaan was divided into seven parts by those measuring, and by that event their inheritance was defined in the North. For they were not able to know previously that their dominion was confined (Masius).
The children of Joseph, that is, of Ephraim and Manasseh, as is manifest, partly from verse 17, where it is so explained; and partly because they mention it as an unreasonable thing, that they, being two, should have out one lot. Spake unto Joshua, that is, expostulated with him, when they went and saw that portion which was allotted to them, and found it much short of their expectation.
[Why hast thou given to me possession of one lot and line?] Question: How is it that they say that one lot was given to them? Responses: 1. They call that one portion, for the possessiong of which one Tribe would be sufficient (Junius, Malvenda, Masius, Lapide, Bonfrerius). 2. Among the children of Joseph the inheritance was not yet divided, which they had received in the drawing of one lot; and so they were pleading that cause together, since they were yet in the like case (Masius). Now, understand this complaint in this way, not that they had actually received a possession smaller than what was due, since we do not read that afterwards their spaces were expanded; but that had received a region in which the Canaanites yet occupied many places (Bonfrerius out of Lapide). These were hoping that they were going to obtain from Joshua, their fellow tribesman, that some peaceful region out of the other tribes might be assigned to them. But Joshua yielded nothing to flesh and blood, but all to righteousness; and he was unwilling to take from other tribes what he might allot to his own (Lapide).
One lot, and one portion; either, 1. Because they really had but one lot, which was afterwards divided by the arbitrators between them. Or, 2. Because the land severally allotted to them was no more than was little enough for one of them. A great people, or numerous; for so the Hebrew word oft signifies.
[And the Lord has blessed me, עַ֥ד אֲשֶׁר־עַד־כֹּ֖ה בֵּֽרְכַ֥נִי יְהוָֽה׃] To such an extent (and thus far [Munster], in such a way thus far [Tigurinus Notes], to such an extent that thus far [Junius and Tremellius], to such an extent hitherto [Vatablus]) He has blessed me (Osiander), that is, to such a number He has been pleased to increase me (Malvenda out of Junius).
 Hebrew: וַֽיְדַבְּרוּ֙ בְּנֵ֣י יוֹסֵ֔ף אֶת־יְהוֹשֻׁ֖עַ לֵאמֹ֑ר מַדּוּעַ֩ נָתַ֙תָּה לִּ֜י נַחֲלָ֗ה גּוֹרָ֤ל אֶחָד֙ וְחֶ֣בֶל אֶחָ֔ד וַֽאֲנִ֣י עַם־רָ֔ב עַ֥ד אֲשֶׁר־עַד־כֹּ֖ה בֵּֽרְכַ֥נִי יְהוָֽה׃
