Zechariah 5:9

The prophet next saw two other women flying through the air with stork wings. Perhaps they were women and not men because of the motherly attention they brought to their task. [Note: Merrill, p. 175.] Storks are strong, motherly birds that are capable of carrying loads a long distance in flight. They were common in Palestine in the spring months when they migrated to Europe (Jeremiah 8:7). [Note: Smith, p. 211.] The word "stork" (Heb. sida) means "faithful one." These women would faithfully carry the ephah and its contents to God’s appointed destination. Some believe they represent agents of evil, perhaps demonic forces. [Note: E.g., Unger, p. 98.] If they were that, however, would they not try to help Wickedness escape? Storks were unclean birds for the Israelites (Leviticus 11:19; Deuteronomy 14:18), so these stork-like women were appropriate carriers of the contaminated basket. They lifted up the ephah into the air flying off from earth to heaven with the divine assistance of the wind (Spirit, Heb. ruah).

"The removal of Wickedness, like the removal of Joshua’s filthy garments (Zechariah 3:4), was an act of free grace on the part of the covenant-keeping (hasid) God." [Note: Baldwin, p. 129.]
