I have dug wells and drunk foreign waters. With the soles of my feet I have dried up all the streams of Egypt.”
We have here the gracious copious answer which God gave to Hezekiah's prayer. The message which he sent him by the same hand (Kg2 19:6, Kg2 19:7), one would think, was an answer sufficient to his prayer; but, that he might have strong consolation, he was encouraged by two immutable things, in which it was impossible for God to lie, Heb 6:18.

HEZEKIAH'S PRAYER. (2Ki. 19:14-34) Hezekiah received the letter . . . and went up into the house of the Lord--Hezekiah, after reading it, hastened into the temple, spread it in the childlike confidence of faith before the Lord, as containing taunts deeply affecting the divine honor, and implored deliverance from this proud defier of God and man.

I have dipped and drunk strange waters - I have conquered strange countries, in which I have digged wells for my army; or, I have gained the wealth of strange countries. With the sole of my feet - My infantry have been so numerous that they alone have been sufficient to drink up the rivers of the places I have besieged.
