Signify
Vine's Expository Dictionary of NT Words [1]
"to give a sign, indicate" (sema, "a sign:" cp. SIGN, No. 1), "to signify," is so translated in John 12:33; 18:32; 21:19; Acts 11:28; 25:27; Revelation 1:1 , where perhaps the suggestion is that of expressing by signs.
"to make plain" (delos, "evident"), is translated "to signify" in 1—Corinthians 1:11 , RV, "it hath been signified" (AV, "declared"); Hebrews 9:8; 12:27; 1—Peter 1:11 , AV (RV, "Point unto"); 2—Peter 1:14 , RV, "sifnified" (AV, "hath showed"). See Point (unto).
"to manifest, make known," is translated "signify" in Acts 23:15; Acts 23:22 , RV (AV, "hath showed"). See Appear , No. 5.
