This seems to have truth to it. If you look at the Wu in Hebrew it resembles a 'Sickle' which is what was used to harvest in ancient times. If you read the book of Revelations 14:14 - 19 ( Mark 4:29; Joel 3:13; Jeremiah 50:16 these precepts explains the function of the sickle in harvest time). It seems as if the jab is to hasten the 'Taken' event, which is what unbelievers called 'the Rapture'. There is no such thing as Rapture but there is a such thing as 'Taken' (read: 2 Esdras 13:15-18 and Matthew 24: 40-41 and 2 Thessalonians 2). The mystery of iniquity is already at work. And according to Genesis 15:16, once the iniquity of the Amorites is full we will witness this event.

So yeah, this video message has some truth to it. And remember that Yahuah says things once and let it speak twice. The sickle harvest the crops and will also harvest the rebellious at heart. It's more than just taking a mark of the beast because if your heart isn't right or just then you can still be 'taken' (heaviness is grievous/sore).
