All the day long - Better, every day. The wish of the slothful man passes into restless, covetous, dissatisfied desire; the righteous, free from that desire, gives without grudging.

He coveteth greedily all the day long,.... The slothful man does, as he has nothing to do to employ his time and his thoughts with; he is always craving something to eat and drink, or wishing he had such an estate, or so much wealth and riches, that he might live as such and such persons do; and this is what his head runs upon all the day long;
but the righteous giveth and spareth not; not gives to the slothful, which does not restrain his desire, as Aben Ezra interprets it; but to the poor and necessitous, to proper objects; a good man will work with his hands, that he may have a sufficiency for himself and his family, and may have something to give to others that are in want; and "he spares not", or withholds not his hands, neither from working nor from giving.

The sin of covetousness marks the sluggard, as the virtue of benevolence the righteous.

26 One always desireth eagerly;
But the righteous giveth and holdeth not back.
Otherwise Fleischer: per totum diem avet avidus, i.e., avarus; but that in התאוּה תּאוה the verb is connected with its inner obj. is manifest from Numbers 11:4; it is the mode of expression which is called in the Greek syntax schema etymologicum, and which is also possible without an adj. joined to the obj., as in the ὕβριν θ ̓ ὑβρίζεις (Eurip. Herc. fur. 706), the Arab. mârâhu miryatn: he had a strife with him. Euchel impossibly: necessities will continually be appeased, which would have required תּתאוּה or מתאוּה. The explanation also cannot be: each day presents its special demand, for כּל־היּום does not mean each day, but the whole day, i.e., continually. Thus we render התאוה with the most general subject (in which case the national grammarians supply המּתאוּה): continually one longs longing, i.e., there are demands, solicitations, wishes, importunate petitions; but still the righteous is not embarrassed in his generosity, he gives as unceasingly (cf. Isaiah 14:6; Isaiah 58:1) as one asks. Thus the perf. is explained, which is related hypothetically to the fut. following: though one, etc.

Coveteth - Spends his whole time in vain and lazy desires. Giveth - By God's blessing upon his industry he procures enough, not only for his own support, but for the relief of others.
