Most versions translate malak Yahweh here as "the angel of the LORD". Brenton Septuagint Translation translated it as "an angel of the Lord".7 The angel of the LORD found her by a spring of water in the wilderness, the spring on the way to Shur.
At this point, the angel spoke in first person authoritatively as if he was the LORD. The wording was similar to what the LORD said to Abram in Genesis 13:8 And he said, “Hagar, servant of Sarai, where have you come from and where are you going?” She said, “I am fleeing from my mistress Sarai.” 9 The angel of the LORD said to her, “Return to your mistress and submit to her.” 10 The angel of the LORD also said to her, “I will surely multiply your offspring so that they cannot be numbered for multitude.”
The angel continued:16 I will make your offspring as the dust of the earth so that if one can count the dust of the earth, your offspring also can be counted.
Here, the language was not in the first person. Still, the angel seemed to be a member of the divine Godhead. Similar language is found in Exodus 24:11 And the angel of the LORD said to her, “Behold, you are pregnant and shall bear a son. You shall call his name Ishmael, because the LORD has listened to your affliction.
Hagar thought the angel was the LORD:1 Then the Lord said to Moses, “Come up to the Lord, you and Aaron, Nadab and Abihu, and seventy of the elders of Israel. You are to worship at a distance, 2a but Moses alone is to approach the Lord.
The angel of the LORD here seems to differ from the LORD-Yahweh but he also seems to be a divine person/witness. They seem to be two distinct witnesses in the Godhead/Divinity.13 So 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.” 14 Therefore the well was called Beer-lahai-roi; it lies between Kadesh and Bered.
