The thought, like that which appears in Zac 5:3-4, and pervades the tragedies of Greek drama, is of a curse, an Ate, dwelling in a house from generation to generation, the source of ever-recurring woes. There is, possibly, a contrast between the "house" or "palace" of the rich oppressor and the lowly shepherd's hut, the "sheep-cote" 2-Samuel 7:8 ennobled only by its upright inhabitants.

The curse of the Lord - No godly people meet in such a house; nor is God ever an inmate there.
But he blesseth the habitation of the just - He considers it as his own temple. There he is worshipped in spirit and in truth; and hence God makes it his dwelling-place.

The curse of the Lord is in the house of the wicked,.... The wicked man, being a transgressor of the law, is under the curse of it; and all that he has, his house, his substance, his very blessings are curses; see Malachi 2:2; he is accursed amidst his greatest affluence, and sometimes from a plentiful estate is reduced to penury and want: and Aben Ezra interprets it, "the curse of want"; and the Vulgate Latin version is, "want from the Lord is", &c.
but he blesseth the habitation of the just; the righteous man, as before described; he is blessed himself, having the righteousness of Christ imputed to him, and his sins forgiven him for his sake; and what he has of worldly substance, though it be ever so little, he has it with a blessing; and therefore it is better than the riches of many wicked men; his house, though it is but a courage, as the word (k) here signifies, is blessed with the presence of God in it; his family, his children, and servants, are blessed, having his instructions and example, and especially when made effectual by the grace of God; as the house of Obededom was blessed for the sake of the ark, so is a just man's house, being a "bethel", an house of God, blessed on account of his worship in it; see 2-Samuel 6:11.

curse . . . wicked--It abides with them, and will be manifested.

The prosperity of the godless, far from being worthy of envy, has as its reverse side the curse:
The curse of Jahve is in the house of the godless,
And the dwelling of the just He blesseth.
מארה (a curse), like מסלּה (a highway, from סלל), is formed from ארר (cf. Arab. harr, detestari, abhorrere, a word-imitation of an interjection used in disagreeable experiences). The curse is not merely a deprivation of external goods which render life happy, and the blessing is not merely the fulness of external possessions; the central-point of the curse lies in continuous disquiet of conscience, and that of the blessing in the happy consciousness that God is with us, in soul-rest and peace which is certain of the grace and goodness of God. The poetic נוה (from נוה = Arab. nwy, tetendit aliquo) signifies the place of settlement, and may be a word borrowed from a nomad life, since it denotes specially the pasture-ground; cf. Proverbs 24:15 (Fleischer). While the curse of God rests in the house of the wicked (vid., Khler on Zac 5:4), He blesses, on the contrary, the dwelling-place of the righteous. The lxx and Jerome read יברך, but יברך is more agreeable, since God continues to be the subject.

The house - Not only upon his own person, but also upon his posterity.
