Matthew 27:1

Now when morning was come (prwia de genomenh). Genitive absolute. After dawn came the Sanhedrin held a formal meeting to condemn Jesus and so ratify the illegal trial during the night ( Mark 15:1 ; Luke 22:66-71 ). Luke gives the details of this second ratification consultation. The phrase used, took counsel (sumboulion elabon) is a Latin idiom (consilium ceperunt) for sunebouleusanto.
