'Fountain' in the Bible

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.

Who doth make my head waters, And mine eye a fountain of tears? And I weep by day and by night, For the wounded of the daughter of my people.

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.
