For I will pour water oh him that is thirsty
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 ( Psalms 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 are signified by the "dry" and "thirsty" ground; for being made sensible of their desolate condition, their barrenness and unfruitfulness, they hungered and thirsted after righteousness; were desirous of Christ and his grace, and more knowledge of him, and eagerly sought after them; and to these are promised the Spirit, and his gifts and graces, compared to water, for its purifying, softening, fructifying, and refreshing nature, and for extinguishing thirst, and giving a real pleasure and delight; see ( Ezekiel 36:25 ) ( John 3:5 ) and the abundance thereof is signified by "floods" of water; for in first conversion especially, there is an abounding, yea a superabounding of the grace of God; it is a well of living water; yea, out of the believer flow rivers of living water, ( John 4:14 ) ( John 7:37 John 7:38 ) ( Romans 5:20 ) ( 1 Timothy 1:14 ) and this grace of the Spirit is always a blessing: and indeed all the blessings of grace go along with it, as to the manifestation and application of them as justification, pardon of sin, adoption; here perhaps a more special regard is had to the extraordinary effusion of the Spirit, on the day of Pentecost, when the apostles of Christ being furnished with his gifts and graces, were fitted to go forth with the "fullness of the blessing" of the Gospel of Christ. The Targum of the whole is,
``for as waters are given upon the thirsty land, and they flow upon the dry land, so will I give my Holy Spirit on thy children, and my blessing upon thy children's children;''a succession of converts in the Christian church.
