Isaiah 32:20

“Blessed [are] ye that sow beside all waters, &c.] In places well watered and moistened, and so fit to receive the seed sown, which grows up, and brings forth much fruit, and amply rewards the pains of the sower, who on that account is happy. These words are directed to the ministers of the Gospel in the latter day; the word is compared to seed, and the preachers of it to sowers of seed, who have a commission to preach the Gospel to every creature; and in the latter day, in the spiritual reign of Christ, to which the whole paragraph refers, they will sow the seed of the word “by many waters”; or among great multitudes of people, signified hereby, and with great success, great numbers both of…”

“While the enemy shall be brought "low," the Jews shall cultivate their land in undisturbed prosperity. all waters--well-watered places (Isa 30:25). The Hebrew translation, "beside," ought rather to be translated, "upon" (Ecc 11:1), where the meaning is, "Cast thy seed upon the waters when the river overflows its banks; the seed will sink into the mud and will spring up when the waters subside, and you will find it after many days in a rich harvest." Before sowing, they send oxen, &c., into the water to tread the ground for sowing. CASTALIO thinks there is an allusion to the Mosaic precept, not to plough with an ox and ass together, mystically implying that the Jew was to have no intercourse…”

“Blessed are ye - The sense of this verse is, that while the enemies of the Jews would be overthrown, they themselves would be permitted to cultivate their lands in security. Instead of predicting this directly, the prophet implies that this would occur, by declaring that those who were permitted to do this were happy. That sow beside all waters - Hebrew, ‘Upon (על ‛al) all waters.’ This may mean that they selected places near running streams as being most fertile; or it may refer, as Lowth supposes, to the manner of sowing grain, and particularly rice, in eastern countries. This is done by casting the seed upon the water. This custom is referred to in Ecclesiastes 11:1 : ‘Cast thy bread,’…”

“Blessed - As the barren forest shall be destroyed, so the fruitful field shall be improved, and bring forth much fruit; which is signified by a declaration of the blessedness of them that sow in it. Waters - In all moist grounds, which are like to yield good fruit. But this also is to be understood of the times of the gospel, and of the great and happy success of the ministers of it. The ox - Which they employed in plowing and sowing the ground. Next: Isaiah Chapter 33”

“Blessed: Isa 19:5-7, Isa 30:23, Isa 55:10, Isa 55:11; Ecc 11:1; Act 2:41, Act 4:4, Act 5:14; Co1 3:6; Jam 3:18 the ox: Isa 30:24; Co1 9:9-11 Next: Isaiah Chapter 33”

“In the face of this double judgment, the prophet congratulates those who will live to see the times after the judgment. "Blessed are ye that sow by all waters, and let the foot of the oxen and asses rove in freedom." Those who lived to see these times would be far and wide the lords of a quiet and fruitful land, cleared of its foes, and of all disturbers of peace. They would sow wherever they pleased, by all the waters that fertilized the soil, and therefore in a soil of the most productive kind, and one that required little if any trouble to cultivate. And inasmuch as everything would be in the most copious abundance, they would no longer need to watch with anxiety lest their oxen and asses…”
