And Abraham rose up early in the morning,
and took bread,
and a bottle of water,
and gave it unto Hagar,
putting it on her shoulder,
and the child,
and sent her away:
and she departed,
and wandered in the wilderness of Beersheba.
Genesis 21:14 KJV

And the water was spent in the bottle,
and she cast the child under one of the shrubs.
Genesis 21:15 KJV

And God opened her eyes,
and she saw a well of water;
and she went,
and filled the bottle with water,
and gave the lad drink.
Genesis 21:19 KJV
