I will pour water; my Spirit and blessing, which is frequently compared to water; and so it is expounded in the latter part of the verse. Upon him that is thirsty: either,
1. Upon him that desires it. Or rather,
2. Upon him that is destitute of it; for what is here thirsty, in the next clause it is called dry ground. My Spirit; the gifts and graces of my Spirit; which expression he seems designedly to use, to lift up the minds and hearts of the Jews from carnal and worldly things, to which they were too much addicted, unto spiritual and heavenly blessings, and thereby to prepare them for the better entertainment of the gospel. My blessing; all the blessings of my covenant, both spiritual and temporal.
