A.T. Robertson Commentary Revelation 6:13

"and the stars of the heaven fell unto the earth, as a fig tree casteth her unripe figs when she is shaken of a great wind." — Revelation 6:13 (ASV)

Her unripe figs (τους ολυνθους αυτης). An old word (Latin grossi) for figs that grow in winter and fall off in the spring without getting ripe (Song of Solomon 2:11f.), here only in N.T. Jesus used the fig tree as a sign of the "end of the world's long winter" (Swete). Cf. Isaiah 34:4; Nahum 3:12.

When she is shaken of a great wind (υπο ανεμου μεγαλου σειομενη). Present passive participle of σειω, "being shaken by a great wind." See Mt 11:7 for the reed so shaken.
