Q: #121. How many days were there between Jesus' ascension to Heaven and Pentecost?
A: There were 10 days between His ascension and Pentecost. How do we know this? Jesus arose from the dead on the Feast of Firstfruits (See: Q: #117 for more on this). A “wave offering” was made on this day (Lev 23:9-10). The Feast of Weeks, also known as Pentecost (from the Greek word “Pentecoste” meaning fiftieth) began 50 days after the wave offering (Lev 23:15-16)(Deut 16:9-10). Jesus was on the Earth for 40 days before His ascension (Acts 1:3). Therefore, 50-40= 10 days.
