Zechariah 12:10, And I will pour upon the house of David, and upon the inhabitants of Jerusalm, the spirit of grace and of supplications: and they shall look upon me whom they have pierced, and they shall mourn for him, as one mourneth for his only son, and shall be in bitterness for him, as one that is in bitterness for his firstborn.
The book of Zechariah is a great book to show the Trinity, in the first chapter of the book of Zechariah we see " the angel of the Lord" , answered and said to the Lord of hosts.
Who is the angel of the Lord?
antheGenesis 16:7-12; 21:17-18; 22:11-18; Exodus 3:2 with Mark 12:26; Judges 2:1-4; 5:23; 6:11-24; 13:3-22; 2 Samuel 24:16; Zechariah 1:12; 3:1; 12:8
NOT THAT JESUS IS AN ANGEL, NO WAY!!!! But this is a title. the angel of the Lord spoke to the Lord of hosts. Zech.1:12 Trinity
Acts 20:28, Take heed therefore unto yourselves, and to all the flock, over the which the Holy Ghost hath made you overseers, to feed the church of God, which (he) hath purchased with his own bood.
(he) referring to Jesus, not the Holy Ghost, " the Holy Ghost was not yet given, because that Jesus was not yet glorified" John 7:39
It is the blood of Jesus that was shed for us! and Paul was talking about Jesus before that verse too, (verse 21. )
To say the Holy Ghost died for us on the Cross, and not Jesus is totally unscripturally, and chickenscratching the Word of God.
