Those that be planted in the house of the Lord - As if plants were reared up in the house of God. The same image, under the idea of the olive tree, occurs in Psalm 52:8. See the notes at that verse. The passage here may refer particularly to those who have been trained up in connection with the church; young plants set out in the sanctuary, and cultivated until they have reached their growth.
Shall flourish in the courts of our God - That is, Having been planted there, they will grow there; they will send out their boughs there; they will produce fruit there. The "courts" of the house of God were properly the areas or open spaces around the tabernacle or the temple (see the notes at Matthew 21:12); but the word came also to denote the tabernacle or the temple itself, or to designate a place where God was worshipped. It has this meaning here. The passage affords an encouragement to parents to train up their children in attendance on the ordinances of public worship; and it shows the advantage of having been born in the church, and of having been trained up in it - an advantage which no one can fully appreciate. The passage may also be regarded as furnishing a proof of what will be the result of being thus "planted" and nurtured in connection with the church, inasmuch as trees carefully planted and cultivated are expected to produce more and better fruit than those which grow wild.

Those that be planted in the house of the Lord - I believe the Chaldee has the true meaning here: "His children shall be planted in the house of the sanctuary of the Lord, and shall flourish in the courts of our God." As these trees flourish in their respective soils and climates, so shall the righteous in the ordinances of God. I do not think there is any allusion to either palm-trees or cedars, planted near the tabernacle or temple.

Those that be planted in the house of the Lord,.... Or being planted (e), that is, everyone of the righteous before mentioned; such are they that are planted out of the wilderness of the world, and into Christ, and are rooted in him, and are planted together in the likeness of his death and resurrection; have the graces of the Spirit of God implanted in them, have received the ingrafted word; and, in consequence of all this, are grafted into the olive tree, the church; or have a place and name there, better than that of sons and daughters, where they are as plants grown up in their youth; and which is here meant by "the house of the Lord", in allusion to the tabernacle, or temple, which had the figure of palm trees on the walls of it: so the Targum interprets it the temple, rendering it,
"his children shall be planted in the sanctuary of the Lord:''
and though it may seem strange that trees should be planted in an house, it should be remembered that the house of the Lord, or the church, is a garden, whose plants are an orchard of pomegranates, Song 4:12, and such are not mere education plants, or such as are merely by outward profession, or only ministerially, planted, but are planted by the Lord himself; and so are choice and pleasant ones, by which God is glorified, and which shall never be plucked up: and these
shall flourish in the courts of our God; like trees in courtyards before houses; alluding to the courts in the tabernacle or temple, where the people worshipped: here the righteous flourish like palm trees, as in the preceding verse, being rooted in Christ, who is the righteous man's root, that yieldeth fruit, and from whom all his fruit is found; but this flourishing is not merely in the leaves of profession, but in the fruits of grace and righteousness, being watered with the dews of divine grace, and having the benefit of the word and ordinances; which are the waters of the sanctuary, that refresh and quicken the trees of righteousness that grow by it; see Ezekiel 47:1. This is referred to the times of the Messiah, and the resurrection, by the ancient Jews (f).
(e) "plantati", Pagninus, Montanus, Junius & Tremellius, &c. (f) Zohar in Leviticus. 7. 1.

The soil in which the righteous are planted or (if it is not rendered with the lxx πεφυτευμένοι, but with the other Greek versions μεταφυτευθέντες) into which they are transplanted, and where they take root, a planting of the Lord, for His praise, is His holy Temple, the centre of a family fellowship with God that is brought about from that point as its starting-point and is unlimited by time and space. There they stand as in sacred ground and air, which impart to them ever new powers of life; they put forth buds (הפריח as in Job 14:9) and preserve a verdant freshness and marrowy vitality (like the olive, 52:10, Judges 9:9) even into their old age (נוּב of a productive force for putting out shoots; vid., with reference to the root נב, Genesis, S. 635f.), cf. Isaiah 65:22 : like the duration of the trees is the duration of my people; they live long in unbroken strength, in order, in looking back upon a life rich in experiences of divine acts of righteousness and loving-kindness, to confirm the confession which Moses, in Deuteronomy 32:4, places at the head of his great song. There the expression is אין עול, here it is אין עלתה בּו. This ‛ôlātha, softened from ‛awlātha - So the Ker - with a transition from the aw, au into ô, is also found in Job 5:16 (cf. עלה = עולה Psalm 58:3; Psalm 64:7; Isaiah 61:8), and is certainly original in this Psalm, which also has many other points of coincidence with the Book of Job (like Ps 107, which, however, in Psalm 107:42 transposes עלתה into עולה).

Planted - Whom God by his gracious providence has fixed there. The house - In its courts; he means in the church of God, whereof all good men are living members.
