If 'the Angel of the Lord" in the Old Testament was the pre-incarnate Jesus (a Christophany); does it mean Christ/the Son/Word blessed Ishmael twice?

**To those who believe that the Angel of the Lord who appears in several situations in the Old Testament was the pre-incarnate Christ:** I have come across many writings and opinions from some within the Evangelical Christian movement, asserting that the "angel of the lord" in the Old Testament, is pre-incarnate Jesus (a Christophany). See, for example: or Google: **"Is Jesus the Angel of the Lord?"** On two ocassions in the Bible, the Angel of the Lord appears to Hagar (Genesis 16:7-13 and Genesis 21:17-19). That is, when Hagar is pregnant and being harshly treated by Sarah and later when Hagar runs out of water after Abraham sends her and her son away as demanded by Sarah and consented to by God. **The Angel of the Lord picks the child's name and blesses him on two separate ocassions (before and after his birth). What are the theological and spiritual implications of the fact that Jesus directly and personally blessed Ishmael twice?** **I am not aware of any Biblical passage of Isaac being blessed by God as a child or having an encounter with the Angel of the Lord**
