Genesis 16:13 - "She gave this name to the Lord who spoke to her: 'You are the God who sees me,' for she said, 'I have now seen the One who sees me.'"
This verse refers to Hagar, a slave girl mistreated by her mistress Sarai (later known as Sarah). Hagar ran away from Sarai's household and was visited by an angel of the Lord, who spoke to her and gave her a message of hope.
In response, Hagar called the Lord "the God who sees me" because she recognized He had seen her distress and intervened on her behalf.
