2. After the fall, man needed to repent and to believe in the coming Christ. This was the essential pre-condition for again being indwelt and infilled by the Holy Ghost. Gen. 3:15-21; 4:1,26; 5:21-23; 6:3,8,9; Heb. 11:3-7.
3. God republished His Ten Commandments to man on Mt. Sinai, with wind and fire, at the inauguration of the first Israelitic Annual Feast of Pentecost. This probably further built upon the prior foundations of the Noachic Harvest Feasts. Gen. 8:20-22 & Acts 14:13-17 cf. Ex. 16:1; 20:1f; 22:29; 23:16-19; 34:22-23.
4. The Old Testament Harvest Feasts were thenceforth celebrated yearly. This foreshadowed the then future great Pentecost Sunday, fifty days after Calvary. Lev. 23:1-22; 25:5-10; Deut. 18:4; Neh. 10:24-39; 13:31; Acts 2:1.
