We read that Yahoshua will be wearing a (white) garment and robe when He returns and that also the malakim will be wearing white. We read that there will be a new covenant or marriage between Yah and the Israylites with Yahoshua standing as the bridegroom and the children of Ysrayl will be in proper garments that are clean and bright (white linen). In white linen part 1 we read that the Levites will be wearing (white) linen as they serve Yah because linen keeps the body cool by wicking away moisture/sweat.
I recently read that Yah wears white. In Daniyah 7:9, it says that Yah’s garment is white as snow. Also, Isaiah said that Yah wears a robe and the train of the robe fills the heavenly temple (Isaiah 6:1).
*Update: 9/27/2015: One thing I should have explained in part 1 is when Yah married the Israylites. It’s a beautiful story that I heard the Israylites tell when I first found out the truth. They began with saying that the whole bible is a love story between Yah and the Israylites, from Genesis to Revelation. They explained that the engagement period started with Yah and Abraham. Yah makes a covenant or promise or engagement with Abraham in Genesis 15. An engagement is an arrangement, commitment, contract or formal contract to be married. Yah formally married Ysrayl in Exodus 24:8 when Moshe sprinkled blood on the people. The blood represented the marriage night when a woman bled. The Israylies also explained that the children of Ysrayl are not divorced from Yah but we are separated or put away. No fallen angel has ever claimed the children of Ysrayl as wife (Read the law of Deuteronomy 24:1-4). Yah is our only husband. Yah says the children of Ysrayl have been unfaithful to Him by spiritually whoring with the fallen ones, see Hoshea 2:2, 16-17 Hoshea3:1, Isaiah 54:5, Yahezqyl 16:31-34. If I’m not mistaken, Yah finally put us away when we were kicked out of the land.
As you read in white linen parts 1 and 2 (Yeremiyah 31), there will be a new covenant or marriage between Yah and the Ysraylites in the future. This time instead of Moshe standing in as the bridegroom, Yahoshua will be our bridegroom. At the wedding we all will be wearing white linen. Yah wears white, Yahoshua will be wearing white. The angels will be wearing white. And the children of Ysrayl will be be wearing white linen.
See Revelation 19:7-10 and Yeremiyah 3:14 The marriage supper of the Lamb. Also Revelation 21:2.
Update 10-17-2015: The Song of Solomon (or Song of the Songs) is a wedding (love) poem about Yah and Ysrayl with Yahoshua as the Bridegroom.
