So for those who understand my previous post about the crept in unawares among the children of Israel of Old Testament history, it reveals the working of the negative side of God's Plan before the foundation of this world, of Lord Jesus being born in the flesh to die on the cross to defeat the devil and death for us. Certain false ones in Jerusalem were already prepared and setup in the house of God from the old crept in unawares that served Satan, waiting for Jesus' 1st coming so as to have Jesus murdered on the cross. And they are the ones who coerced the rest of the unbelieving Jews to agree to have Jesus crucified, even yelling out, "crucify Him!" (John 19:6)
Matt 27:20
20 But the chief priests and elders persuaded the multitude that they should ask Barabbas, and destroy Jesus.
KJV
Notice also the band that came to arrest Jesus to crucify Him...
Matt 26:47
47 And while he yet spake, lo, Judas, one of the twelve, came, and with him a great multitude with swords and staves, from the chief priests and elders of the people.
KJV
Those were not Roman soldiers that came to arrest Lord Jesus. They were a band of armed men sent by the chief priests and elders, their men, that's who arrested Jesus.
