Wells

Defend me, therefore, common sense, say I, From reveries so airy, from the toil Of dropping buckets into empty wells, And growing old in drawing nothing up!

—Cowper,William

As for myself, I walk abroad o'nights And kill sick people groaning under walls: Sometimes I go about and poison wells.

—Marlowe, Christopher

Therefore with joy shall ye draw water out of the wells of salvation.

—Bible (Old Testament)
