'Living Water' in the Bible

And Isaac's servants dig in the valley, and find there a well of living water,

A fount of gardens, a well of living waters, And flowings from Lebanon!

For two evils hath My people done, Me they have forsaken, a fountain of living waters, To hew out for themselves wells -- broken wells, That contain not the waters.

The hope of Israel is Jehovah, All forsaking Thee are ashamed, And 'My apostates' in the earth are written, For they have forsaken Jehovah, A fountain of living waters.

And it hath come to pass, in that day, Go forth do living waters from Jerusalem, Half of them unto the eastern sea, And half of them unto the western sea, In summer and in winter it is.
