1: Ἤδη (Strong'S #2235 — Adverb — ede — ay'-day )

is always used of time in the NT and means "now, at (or by) this time," sometimes in the sense of "already," i.e., without mentioning or insisting upon anything further, e.g.,  1—Timothy 5:15 . In  1—Corinthians 4:8;  1—John 2:8 , the RV corrects the AV "now," and, in  2—Timothy 4:6 , the AV, "now ready to be," by the rendering "already."
