Isaiah 41:17

When the poor and needy seek water, and there is none, and their tongue faileth for thirst, I the LORD will hear them, I the God of Israel will not forsake them.

When the poor and needy seek water, and there is none, and their tongue faileth for thirst,.... This is to be understood not literally, but spiritually; not of their outward circumstances, though the people of God are for the most part the poor of the world, and in need of the good things of it, hungry and thirsty, and naked; but of their spiritual estate: as in Christ they need nothing; but in themselves, and at different times, and in different frames, want many things; as larger discoveries of the love of God, fresh supplies of grace from Christ, more spiritual light and liveliness, fresh strength and comfort, fresh views of pardon and righteousness, fresh food for faith, and more grace of every sort to help them in their time of need; and which they seek for at the throne of grace, and in public ordinances, and sometimes they can find none, or it is a long time ere they obtain any: they thirst after doctrine, as the Targum, after the word and ordinances, and sometimes their circumstances are such, they cannot come at them; after communion with God, and spiritual comfort, and cannot enjoy it, being in a place where is no water; and after the blessings of grace, and can have no application of them; see Psalms 42:1, this may represent in a great measure the state of the church under the ten persecutions of the Heathen emperors, or when obliged to fly into the wilderness from the wrath of the dragon,

Revelation 12:6:

I the LORD will hear them; their cries and prayers, and answer them, and supply their wants, who is the Lord God Almighty, and can help them, the Lord that changes not, and therefore they shall not be consumed:

I the God of Israel will not forsake them; neither their persons, nor his work of grace upon them, but will support them, and provide for them, and carry on his work in them; of which they may be assured, because he is the God of Israel, their covenant God and Father.
