Parallel
Judges 15:19
Brenton's English Septuagint · Berean Standard Bible
And God broke open a hollow place in the jaw, and there came thence water, and he drank; and his spirit returned and he revived: therefore the name of the fountain was called ‘The well of the invoker,’ which is in Lechi, until this day.
So God opened up the hollow place in Lehi, and water came out of it. When Samson drank, his strength returned, and he was revived. That is why he named it En-hakkore (note: En-hakkore means the spring of him who calls.), and it remains in Lehi to this day.
