Zechariah 2:9-1 - Yahweh sent me

Zechariah 2:9-11 (KJV) For, behold, I will shake mine hand upon them, and they shall be a spoil to their servants: and ye shall know that the LORD of hosts hath sent me.
Sing and rejoice, O daughter of Zion: for, lo, I come, and I will dwell in the midst of thee, saith the LORD.
And many nations shall be joined to the LORD in that day, and shall be my people: and I will dwell in the midst of thee, and thou shalt know that the LORD of hosts hath sent me unto thee.

The problem with the trinitarian view of these verses is selective placement of speech marks to try and make it look like Yahweh [God the Father] is sending Yahweh [God the son].

Yahweh doesn't send Yahweh, because Yahweh is the personal name of one person.

The surrounding context makes it clear there is an angel speaking. Let's look at the NET version of verse 9 and how they place the speech marks.

NET Bible
"I am about to punish them in such a way," he says, "that they will be looted by their own slaves." Then you will know that the LORD who rules over all has sent me.

You can see that it is Yahweh speaking in the speech marks and somebody else speaking outside the marks, the angel who was sent by Yahweh. The angel of the Lord.

And again in verse 11. Same format. God in speech marks. Angel outside.

NET Bible
"Many nations will join themselves to the LORD on the day of salvation, and they will also be my people. Indeed, I will settle in the midst of you all." Then you will know that the LORD who rules over all has sent me to you.
