Besides the feasts of the Lord there are also the feasts that were feasted according to the tradition of the elders in Judea.
For example, “the feast of the dedication” (John. 10:22); there is no such feast in the Law of Moses. The Lord said to the Jews: “Did not Moses giue you the Law, and yet none of you keepeth the Law? “ (John.7:19) “For had ye beleeued Moses, ye would haue beleeued me: for he wrote of me”. (John. 5:46)
The “Iewes Passeouer”(John.11:55) -- “þe feast of vnleuened bread”(Luke22:1)(15 Nisan) -- “a feast of the Iewes” (John.6:4), “the feast of the dedication” (John 10: 22) and “Easter” (Acts.12:4) are no “the feasts of the Lord” (Lev.23:37)
The feasts of the Lord testify about Jesus Christ. The feasts which were "born" apocryphal books, testify about “another Iesus” (2Kor.11:4) and “another Gospel”;
“your appointed Feasts my soule hateth” (Is.1:14)
