The Lord sees Hagar
Hagar fled to the wilderness from her harsh mistress Sarai when pregnant with Ishmael. The angel of the Lord saw her there by a spring of water on the way to Shur and blessed her. In response, she called the name of the Lord who spoke to her, “You are a God of seeing,” for she said, “Truly here I have seen him who looks after me.”
The well was called Beer-lahai-roi, and it lies between Kadesh and Bered.
God's provision for Ishmael
After Hagar and Ishmael were cast out from Abraham's house, they began to ran out of water. Hagar set the child under a bush, went about a bowshot's distance away, and wept, saying, "Let me not look on the death of the child." God heard Ishmael's voice, and the angel of God called to Hagar from heaven, saying, "What troubles you, Hagar? Fear not, for God has heard the voice of the boy where he is. Up! Lift up the boy, and hold him fast with your hand, for I will make him into a great nation." God opened her eyes, and she saw a well of water. She refilled her skin and gave the boy a drink.

Abraham and Abimelech's covenant
Abimelech and Phicol acknowledged that God was with Abraham and asked him to return their kindness to him and his descendants, and he swore to it. When Abraham reproved Abimelech about the well his servants seized, Abimelech claimed ignorance. Abraham gave him sheep and oxen and made a covenant, setting 7 ewe lambs apart as witness that he dug this well. The place was called Beersheba. Abimelech and Phicol returned to Philistia, and Abraham planted a tamarisk tree and called on the name of the Lord, the Everlasting God.

Abraham's servant finds a wife for Isaac by the well in Nahor in Mesopotamia
Abraham's servant took 10 of his master's camels with choice gifts to find Isaac a wife from the city of Nahor in Mesopotamia. He made the camels kneel down outside the city by the well of water at the time of evening when women draw water. He asked, "O Lord, God of my master Abraham, please grant me success today and show steadfast love to my master Abraham. Behold, I am standing by the spring of water, and the daughters of the men of the city are coming out to draw water. Let the young woman to whom I shall say, ‘Please let down your jar that I may drink,’ and who shall say, ‘Drink, and I will water your camels’—let her be the one whom you have appointed for your servant Isaac. By this I shall know that you have shown steadfast love to my master.”
Before he finished speaking, Rebekah came out with her water jar on her shoulder. The servant ran to meet her and asked for a little water to drink, and she said, "Drink, my lord." She also said, "I will draw water for your camels also, until they have finished drinking." She quickly emptied her jar into the trough and ran again to the well to draw water, and she drew for all his camels. The man gazed in silence to learn whether the Lord had prospered his journey or not.
When the camels finished drinking, he gave her a ring and bracelets of gold and told her his mission. Her brother Laban ran out to the spring and told him he prepared the house and a place for the camels, so the servant unharnessed the camels, gave them straw and fodder, and spent the night with Rebekah's family, leaving with her in the morning.
(Genesis 24)
Jonathan and Ahimaaz hide in a well in Bahurim while performing spy activities during Absalom's rebellion
Hushai sent word to King David from Absalom's court via the priests, telling him how to flee Absalom. The priests' sons, Jonathan and Ahimaaz, waited at En-rogel and were sent word by a female servant, but a young man saw their activity anyway and reported it to Absalom. The men fled and hid in a man's well at Bahurim, and the woman covered the well and scattered grain over it to conceal it. She told Absalom's men when they came searching that they had gone over the brook of water. When they gave up the search, the men were able to continue on to David. (2 Samuel 17)
