Zechariah 5, Vision #7 the Woman in the Basket.
The prophet Zechariah was born in Babylon and left with the first remanent freed by Cyrus the Great after 70 years of captivity. Zechariah returned to Judah in 538 B.C. in the second year of Darius. He was instrumental in stirring the hearts of the Israeli people to complete the rebuilding of the temple 516 - 515 B.C., after a series of failed and forgotten attempts. Before the temple could be built, wickedness had to be removed.
Yahweh called Zechariah as a messenger to receive visions of prophecies in the year 520 – 519 B.C., twenty years after the fall of Babylon. Zechariah is in Judah when he receives his visions from the angel.
Then the angel who was speaking with me went out and said to me, “Lift up now your eyes and see what this is going forth.” I said, “What is it?” And he said, “This is the ephah going forth (moving, in motion).” Again, he said, “This is their appearance (iniquity) in all the land (and behold, a lead cover was lifted up); and this is a woman sitting inside the ephah.” Then he said, “This is Wickedness!” And he threw her down into the middle of the ephah and cast the lead weight on its opening. Then I lifted up my eyes and looked, and there two women were coming out with the wind in their wings; and they had wings like the wings of a stork, and they lifted up the ephah between the earth and the heavens. I said to the angel who was speaking with me, “Where are they taking the ephah?” Then he said to me, “To build a temple for her in the land of Shinar; and when it is prepared, she will be set there on her own pedestal.” Zechariah 5:5-11 NASB
An ephah represents a system of measure; it was a container used to measure volume for dry goods such as barley or fine flour. It was used in commerce and trade for the storing, weighing, buying and selling of dry goods. It wasn’t very big, equal to about a bushel 35 liters or 6 gallons.
