Divine plurality in Zechariah 2 — Yahweh sent by Yahweh

Zechariah 2:6-11 contains three instances where "Yahweh" is sent by "Yahweh": verse 8 (Lord of hosts sent me to the nations), verse 9 (then you will know the Lord of hosts has sent me), and verse 11 (you will know the Lord of hosts has sent me to you). The alternative interpretation that Zechariah is interjecting is refuted by Zechariah 4:8-9, where the word of the Lord speaks to Zechariah saying "then you will know the Lord of hosts has sent me to you" — it is the word of the Lord saying this, not Zechariah. This is evidence of divine plurality — the concept of multiple divine persons — embedded in the Hebrew scriptures.
