“For I will pour water oh him that is thirsty, &c.] Or rather upon the thirsty land, as the Targum; and so the Syriac version, “in a thirsty place”; as a dry land is a thirsty land; it thirsts for water, gapes and opens for it: (see <196301>Psalm 63:1) “and floods upon the dry ground”; large quantities of rain to moisten it, and make it fruitful; these figurative expressions are explained in the next clauses: I will pour my Spirit upon thy seed, and my blessing upon thine offspring; by which “seed” and “offspring” are meant the spiritual seed of this remnant or little church of Christ among the Jews, in the first times of the Gospel: such as should be regenerated and converted in it, and who…”
