1Now Sarai, Abram’s wife, bore him no children. She had a servant, an Egyptian, whose name was Hagar. 2Sarai said to Abram, “See now, Yahweh has restrained me from bearing. Please go in to my servant. It may be that I will obtain children by her.” Abram listened to the voice of Sarai. 3Sarai, Abram’s wife, took Hagar the Egyptian, her servant, after Abram had lived ten years in the land of Canaan, and gave her to Abram her husband to be his wife. 4He went in to Hagar, and she conceived. When she saw that she had conceived, her mistress was despised in her eyes. 5Sarai said to Abram, “This wrong is your fault. I gave my servant into your bosom, and when she saw that she had conceived, she despised me. May Yahweh judge between me and you.”
6But Abram said to Sarai, “Behold, your maid is in your hand. Do to her whatever is good in your eyes.” Sarai dealt harshly with her, and she fled from her face.
7Yahweh’s angel found her by a fountain of water in the wilderness, by the fountain on the way to Shur. 8He said, “Hagar, Sarai’s servant, where did you come from? Where are you going?”
She said, “I am fleeing from the face of my mistress Sarai.”
9Yahweh’s angel said to her, “Return to your mistress, and submit yourself under her hands.” 10Yahweh’s angel said to her, “I will greatly multiply your offspring, that they will not be counted for multitude.” 11Yahweh’s angel said to her, “Behold, you are with child, and will bear a son. You shall call his name Ishmael, because Yahweh has heard your affliction. 12He will be like a wild donkey among men. His hand will be against every man, and every man’s hand against him. He will live opposed to all of his brothers.”
13She called the name of Yahweh who spoke to her, “You are a God who sees,” for she said, “Have I even stayed alive after seeing him?” 14Therefore the well was called Beer Lahai Roi. Behold, it is between Kadesh and Bered.
15Hagar bore a son for Abram. Abram called the name of his son, whom Hagar bore, Ishmael. 16Abram was eighty-six years old when Hagar bore Ishmael to Abram.
“LORD” (Yahweh, Heb. יְהוָ֞ה (Gen. 3:1; 4:1, 9; 16, 11; Ex. 3:14, 18; Lev. 26:2; Num. 3:45) Strong’s #3068: Strictly speaking, the only personal name of God belonging to Him alone, and the most significant name of God found in the Old Testament (over 5000 times). Yahweh is the approximate (and likely) pronunciation of the tetragrammaton, the four-letter word YHWH. When Moses asked what His name was to take back to the Hebrews in Egypt, God replied, “I AM THAT I AM (אֶֽהְיֶ֖ה אֲשֶׁ֣ר אֶֽהְיֶ֑ה ehyeh esher ehyeh): and he said, Thus shall you say to the children of Israel, I AM (אֶֽהְיֶ֖ה, ehyeh, 1st person singular, giving God's declaration of His name) has sent me to you” (Ex. 3:14). Thus God revealed to Moses the very essential meaning of His name as Yahweh (יְהוָ֞ה, Yahweh, 3rd person singular, the response of the people of God, He is). There is a strong indication that Jesus (or Yeshua, Yahweh is salvation) used this name and its divine implication to apply to himself when he said, “Before Abraham was, I AM” (ἐγὼ εἰμί, egō eimi) (Jn. 8:58). Thus, the very Person who spoke to Moses out of the burning bush was the very same Person who addressed the startled Jews in the Gospel of John.
