For the Lord's portion is his people. This is the main point, that God was moved by nothing but His own good pleasure to make so much of this people, who had been derived from a common origin with all others: for when he says, that Jacob was the portion of Jehovah, and the lot of His inheritance, he does not mean that there was anything better in them than in others, but he assigns the reason why God preferred this one nation to the rest of mankind; viz., because He took it to Himself as His hereditary portion, which dignity depends upon His gratuitous election.
The Lord's portion is his people - What an astonishing saying! As holy souls take God for their portion, so God takes them for his portion. He represents himself as happy in his followers; and they are infinitely happy in, and satisfied with, God as their portion. This is what is implied in being a saint. He who is seeking for an earthly portion, has little commerce with the Most High.
For the Lord's portion is his people, Jacob is the lot of his inheritance. This is the reason why the Lord so early provided a portion or inheritance for the children of Israel in the land of Canaan; because they were his part, his portion, his inheritance, which he chose by lot for himself, or allotted to himself; whom he chose to be his special and peculiar people; for though all the world is his, he only reserved a part for himself, which he separated from all the rest, and considers as his portion and inheritance, see Psalm 33:12; thus the spiritual Israel of God, as they are his people, whom he has chosen, taken into covenant, given to Christ, and are redeemed and saved by him; they are his part or portion, separated by distinguishing grace from the rest of the world; and are the inheritance of Christ, who is appointed heir of all things, and is an unalienable inheritance; and is obtained by lot, or rather is measured out by a rod or line; by the line of electing grace, by which the church and people of God are circumscribed, marked out, and distinguished from others; and by the line and rule of the sacred Scriptures, which are the measure and standard of faith and practice, of worship and discipline to them.
God did this, because He had chosen Israel as His own nation, even before it came into existence. As the Lord's people of possession (cf. Deuteronomy 7:6; Deuteronomy 10:15, and Exodus 19:5), Israel was Jehovah's portion, and the inheritance assigned to Him. חבל, a cord, or measure, then a piece of land measured off; here it is figuratively applied to the nation.
His people - It is no wonder God had so great a regard to this people, for he chose them out of all mankind to be his peculiar portion.
