When they were but very few in number The prophet here recounts the benefits which God had conferred upon the holy fathers from the commencement, to manifest that even long before the deliverance from Egypt, the covenant was not ineffectual. The great object aimed at in this recital, is to show that ever since God took Abraham under his protection, he cherished him in a wonderful manner, and also that his fatherly love and care were displayed in maintaining and defending the other two patriarchs. When it is said, that they were but very few in number, the power of God by this circumstance is not only magnified, but the cause why he was so beneficent towards them is also pointed out. We must then, in the first place, attend to this, that the prophet, lest the Jews should arrogate anything to themselves, expressly declares, that their fathers had experienced the divine favor, even when they were feeble and despised, wandering from place to place, in every respect poor and miserable according to the flesh. Thus also Moses reproaches them, "The Lord did not set his love upon you, nor choose you, because ye were more in number than any people; for ye were the fewest of all people; but because the Lord loved you." Deuteronomy 7:7, 8, In short, in the choosing of this people, no regard was had either to number, or to any excellence whatever. There was only the house of Abraham, and yet it was barren. Isaac was compelled to banish to a distance from him one of his two sons, and he saw the other cut off from his family. The house of Jacob was indeed more fruitful, but it was nevertheless of a low condition. Besides, they were not only ignoble and despised when sojourning in a strange land, but famine, and the want of other things also, compelled them frequently to go from one place to another. All these things being taken into view, the consideration of human worth falls to the ground, and it is clearly seen, that all the blessings which God had bestowed upon them flowed from no other fountain than his own free love. And the cause of this love is not to be sought for out of himself. If the Holy Spirit is so careful in magnifying the grace of God in these earthly blessings, how much more must he observe this rule, when the subject of which he speaks is the heavenly inheritance! When it is said, that they walked about from nation to nation, this intimates the more plainly how wonderfully the divine protection was displayed in preserving them. Had they found any quiet nest in which to repose, such comfort would have been a notable sign of the divine goodness; but when they were as exiles in divers countries, and were driven from one place to another with bitter scorn, as chaff is driven about by the wind, the guardianship which God exercised over them shone forth much more conspicuously. Since their life everywhere hung only by a thread, and the changing of their place of sojourn exposed them from time to time to fresh injuries, it is evident that it was the divine power alone which preserved them in safety.

When they were but a few men in number - literally, "In their being people of number, very little." That is, They could then be easily numbered, and they were so few that they could not take possession of it themselves. This is in contrast with the promise then made to them that they should be in number as the stars, and as the sand on the sea shore.
And strangers in it - Foreigners. They were mere sojourners. They did not become incorporated with the people of the land. They did not acquire property there. They were regarded and treated as belonging to a foreign people. See the notes at Hebrews 11:9.

But a few men - When all appearances were against them, and nothing but the arm of God could have brought them through their difficulties, and given them a settlement in the promised land.

When they were but a few men in number,.... Or "men of number" (d), that might easily be numbered; see Genesis 34:30, when this covenant, promise, and oath, were first made to Abraham, he was alone, and had no child; and when his posterity were increased in Jacob's time, and sojourned in Egypt, they were but few, though greatly enlarged when they came out of it: in comparison of other nations, they were the fewest of all people, and therefore had this grant of Canaan, not for their numbers any more than their goodness. And this circumstance is mentioned to show the unmerited goodness of God unto them; see Deuteronomy 7:6. And so the Lord's people, to whom he gives the kingdom of heaven, are a little flock; they are only a few that find the way to eternal life, Luke 12:32.
Yea, very few; or "as a little thing" (e): so were the people of Israel a little contemptible body of men in the eyes of others, and in comparison of them. And such are the saints in this world; "the filth of it", and the "offscouring of all things";
yea, things that are not; that scarce deserve, in the opinion of men, to be reckoned entities or beings. And strangers in it; as Abraham, Isaac, and Jacob, were, Hebrews 11:9, and so are the people of God, who are the heirs of the heavenly Canaan. These are strangers to the men of the world, who know them not; and the men of the world to them; with whom they have no conversation and fellowship in things sinful and criminal; for which they late despised by the world: yet these are the fellow citizens of heaven, and of the household of God, which shows his discriminating grace.

few . . . in number--alluding to Jacob's words (Genesis 34:30), "I being few in number."
yea, very few--literally, "as a few," that is, like fewness itself (compare Isaiah 1:9).
strangers--sojourners in the land of their future inheritance, as in a strange country (Hebrews 11:9).

The poet now celebrates the divine preservation which had sway over the small beginnings of Israel, when it made the patriarchs proof against harm on their wanderings. "Men of number" are such as can be easily counted, vid., the confessions in Genesis 34:30; Deuteronomy 26:5; ויּתהלּכוּ places the claim upon the hospitality at one time of this people and at another time of that people in the connection with it of cause and effect. כּמעט, as a small number, only such a small number, signifies, as being virtually an adjective: inconsiderable, insignificant, worthless (Proverbs 10:20). בּהּ refers to Canaan. In Psalm 105:13 the way in which the words גּוי and עם alternate is instructive: the former signifies the nation, bound together by a common origin, language, country, and descent; the latter the people, bound together by unity of government.
(Note: For this reason a king says עמּי, not גּויי; and גּוי only occurs twice with a suffix, which refers to Jahve (Psalm 106:5; Zephaniah 2:9); for this reason גּוי, frequently side by side with עם, is the nobler word, e.g., in Deuteronomy 32:21; Jeremiah 2:11; for this reason עם is frequently added to גּוי as a dignitative predicate, Exodus 33:13; Deuteronomy 4:6; and for this reason גּוים and עם ה are used antithetically.)
The apodosis does not begin until Psalm 105:14. It is different in connection with בּהיותכם in the text of the chronicler, and in this passage in the Psalter of the Syriac version, according to which Psalm 105:12 ought to be jointed to the preceding group. The variation ומממלכה instead of מממלכה is of no consequence; but לאישׁ (to any one whomsoever) instead of אדם, in connection with הניח, restores the current mode of expression (Ecclesiastes 5:11; 2-Samuel 16:11; Hosea 4:17) instead of one which is without support elsewhere, but which follows the model of נתן, נטשׁ, Genesis 31:28 (cf. supra p. 171); whilst on the other hand ובנביאי instead of ולנביאי substitutes an expression that cannot be supported for the current one (Genesis 19:9; Ruth 1:21). In Psalm 105:14 the poet has the three histories of the preservation of the wives of the patriarchs in his mind, viz., of Sarah in Egypt (Genesis. 12), and of Sarah and of Rebekah both in Philistia (Psalm 20:1-9, Psalm 26:1-12, cf. especially Psalm 26:11). In the second instance God declares the patriarch to be a "prophet" (Psalm 20:7). The one mention has reference to this and the other to Genesis. 17, where Abram is set apart to be the father of peoples and kings, and Sarai to be a princess. They are called משׁיהים (a passive form) as eing God-chosen princes, and נביאים (an intensive active form, from נבא, root נב, to divulge), not as being inspired ones (Hupfeld), but as being God's spokesmen (cf. Exodus 7:1. with Exodus 4:15.), therefore as being the recipients and mediators of a divine revelation.
