Verse 43: And the LORD gave unto Israel (Gen. 13:15; 15:18; 26:3; 28:4, 13) all the land which he sware to give unto their fathers; and they possessed it, and dwelt therein.
[And He gave…all the land] Question: How is this true, since the Canaanites were holding a great part of the land? Responses: 1. He gave with respect to right and dominion in the very distribution of the lots (Lapide, Bonfrerius). 2. And He gave a far greater part with respect to actual use and possession. 3. He gave all as He decreed and decided that He was going to give (Bonfrerius); not indeed at one and the same time, but successively, lest wild beasts multiply (Lyra, Lapide, Masius, Bonfrerius). See Joshua 13 (Lyra), and Exodus 23:29, 30 (Bonfrerius). Now, this condition, which He had added to His promise, was not burdensome, but advantageous, to the Israelites (Lapide out of Tostatus). He gave the land, as much as they were able to occupy to this point; and what parts the Canaanites hold, those they as tenants merely maintain and cultivate for the Israelites, as masters/owners, lest they run wild; and then the Canaanites were going to yield, when the Israelites, enlarged with offspring, were able themselves to come to occupy their estates. 4. The promises of God were according to the covenant, and under the condition that they fulfill their duty (Masius).
The LORD gave all the land, etc.: He gave them the right to all, and the actual possession of the greatest part of it, and power to possess the rest as soon as it was needful and convenient for them, which was by degrees, when their numbers were increased, etc., Exodus 23:29, 30, and the absolute dominion of all the people remaining in it.
Verse 44: (Josh. 11:23; 22:4) And the LORD gave them rest round about, according to all that he sware unto their fathers: and (Deut. 7:24) there stood not a man of all their enemies before them; the LORD delivered all their enemies into their hand.
[And peace was given by Him, וַיָּ֙נַח יְהוָ֤ה לָהֶם֙] And He gave rest to them (Septuagint, Arabic, Montanus, Junius and Tremellius). Question: How is this true, since the Danites, driven into the mountains, were compelled to relinquish the valleys to the Canaanites? Response: It is true κατὰ συνεκδοχὴν, synecdochically, for most of the other Tribes were superior to their enemies. Just as in 1 Corinthians 15:5, He appeared to the twelve, although Judas, having been hanged, had burst asunder. But I, nothing doubting, would say that neither the Danites nor others fought with their enemies unsuccessfully, except after the death of Joshua and the elders, when with piety decaying the affairs of the Israelites also began to grow worse (Masius).
[And no one dared to resist] Hebrew: not a man stood…of all their enemies, namely, whom the Israelites attacked, and were hostilely provoked by them (Junius, Malvenda).
There stood not a man of all their enemies before them: To wit, all the days of Joshua, by comparing Joshua 1:5, for afterwards it was otherwise with them.
Verse 45: (Josh. 23:14) There failed not ought of any good thing which the LORD had spoken unto the house of Israel; all came to pass.
[Not even one word…was void, לֹֽא־נָפַ֣ל דָּבָ֔ר] Not a word of every good word has fallen (Montanus, similarly the Septuagint, Jonathan, Syriac). No matter has perished (or, been omitted [Masius]) of all the good promises, etc. (Arabic, similarly Junius and Tremellius, Masius). The execution of that Divine benediction promised to the obedient, Deuteronomy 11:27, is here called a good matter (Masius).
