Matthew Henry Commentary Judges 15:18-20

"And he was sore athirst, and called on Jehovah, and said, Thou hast given this great deliverance by the hand of thy servant; and now shall I die for thirst, and fall into the hand of the uncircumcised. But God clave the hollow place that is in Lehi, and there came water thereout; and when he had drunk, his spirit came again, and he revived: wherefore the name thereof was called En-hakkore, which is in Lehi, unto this day. And he judged Israel in the days of the Philistines twenty years." — Judges 15:18-20 (ASV)

So little notice did the men of Judah take of their deliverer, that he was ready to perish for lack of a drink of water. Thus, the greatest slights are often put upon those who perform the greatest services.

Samson prayed to God in this distress. Those who forget to attend God with their praises may be compelled to attend Him with their prayers. Past experiences of God's power and goodness are excellent pleas in prayer for further mercy. He pleads his being exposed to God's enemies; our best pleas are taken from God's glory.

The Lord sent him timely relief. The place of this action was called Lehi, its name derived from the jaw-bone. And in the place so named, God caused a fountain suddenly and timely to open, near Samson.

We should be more thankful for the mercy of water, if we considered how difficult it is to be without it. Israel submitted to him whom they had betrayed. God was with him; henceforth they were directed by him as their judge.
