Send a plentiful rain; either,
1. In the wilderness; where they oft wanted water, and were by God's extraordinary care supplied with it. Or rather,
2. In the land of Canaan, which he calls God's inheritance in the next words; as also Exodus 15:17, and in many other places of Scripture; in which God's people are said to dwell in the next verse, of which, and the things done in it, lie speaks in the following verses, and which, being destitute of those constant supplies from the overflowings of a great river which Egypt enjoyed, God took a special care to supply with rain as occasion required; of which see Deuteronomy 11:10,11. Confirm; or, stablish, or support, or sustain. Thine inheritance; either thy people; or rather thy land, as was now said. Weary; dry and thirsty, and parched with excessive heat, and ready to faint for want of rain: compare Psalms 63:1.
