Charles Ellicott Commentary Luke 6:44

"For each tree is known by its own fruit. For of thorns men do not gather figs, nor of a bramble bush gather they grapes." — Luke 6:44 (ASV)

Of thorns men do not gather figs.—The form of the illustration differs slightly from that in Saint Matthew, where the thorns are connected with grapes, and the figs with thistles. The word for “bramble bush” is the same as that used in Luke 20:37, and in the LXX version of Exodus 3:2-4, and Deuteronomy 33:16, for the burning “bush” on Sinai. We may note further the use of a different Greek word (that specially connected, as in Revelation 14:18-19, with the gathering of the vintage) for the second “gather” in Saint Luke’s report.
