³ And in the merkavah hashlishit susim levanim (white horses); and in the merkavah harevi’it speckled, powerful susim.

⁴ Then I answered and said unto the malach that spoke with me, What are these, adoni?

⁵ And the malach answered and said unto me, These are the arba ruchot HaShomayim, which go forth from standing before Adon Kol HaAretz [T.N. See Malachi 3:1 where Moshiach is referred to similarly].
