You are completely off the track. No need for hundreds of words. Both the Father and the Son are called YHWH (Yahweh) in the OT. If you have a problem with that, you had better deal with it.
If you have a problem with my post, then you are criticizing (not me, but) RSV, NRSV; GNB; MLB; NAB (1970); NAB (1991); LB; Mo; AT; JB; NJB; NLV; BBE; and Byington translations of Zech. 12:10 and most (all?) translations of John 19:37.
