Vine's Expository Dictionary of NT Words
primarily "what can be taught," then, "taught," is used (a) of persons, John 6:45; (b) of things, 1 Corinthians 2:13 (twice), "(not in words which man's wisdom) teacheth, (but which the Spirit) teacheth," lit., "(not in words) taught (of man's wisdom, but) taught (of the Spirit)."
"God-taught" (Theos, "God," and No. 1), occurs in 1 Thessalonians 4:9 , lit., "God-taught (persons);" while the missionaries had "taught" the converts to love one another, God had Himself been their Teacher. Cp. John 6:45 (see No. 1).
