The New John Gill Exposition of the Entire BibleGenesis 26:19
And Isaac's servants digged in the valley…
In the valley
of Gerar, as the Septuagint version expresses it:
and found there a well of springing water;
or "living water" F12, which
continually flows, as Aben Ezra rightly interprets it: hence this
phrase is used of the perpetual and ever living graces of the Spirit of
God, (John 4:10,11) (7:38) .
F12 (Myyx Mym) "aquarum viventium", Pagninus, Montanus, Drusius.
