Persecution.
In fact, they would. As explained in Scripture by the great theologian, Gamaliel, it was not just criminals who were condemned to death in the Roman system. Others who were condemned, were rebels. And Israel had seen its share of rebels who were fighting the Roman Government and seeking to free their people from oppression.
Acts 5:33 When they heard that, they were cut to the heart, and took counsel to slay them.
34 Then stood there up one in the council, a Pharisee, named Gamaliel, a doctor of the law, had in reputation among all the people, and commanded to put the apostles forth a little space;
35 And said unto them, Ye men of Israel, take heed to yourselves what ye intend to do as touching these men.
36 For before these days rose up Theudas, boasting himself to be somebody; to whom a number of men, about four hundred, joined themselves: who was slain; and all, as many as obeyed him, were scattered, and brought to nought.
37 After this man rose up Judas of Galilee in the days of the taxing, and drew away much people after him: he also perished; and all, even as many as obeyed him, were dispersed.
38 And now I say unto you, Refrain from these men, and let them alone: for if this counsel or this work be of men, it will come to nought:
39 But if it be of God, ye cannot overthrow it; lest haply ye be found even to fight against God.
Thus, in using this phrase, some might have thought that Jesus was asking them to join a rebellion, understanding that they would have much to suffer. There were other sayings of His that could be interpreted that way. For example:
Matthew 10:34 Think not that I am come to send peace on earth: I came not to send peace, but a sword.
Matthew 5:10 Blessed are they which are persecuted for righteousness’ sake: for theirs is the kingdom of heaven.
Matthew 20:22 But Jesus answered and said, Ye know not what ye ask. Are ye able to drink of the cup that I shall drink of, and to be baptized with the baptism that I am baptized with? They say unto him, We are able.
Matthew 10:22 And you will be hated by all for My name’s sake. But he who endures to the end will be saved. 23 When they persecute you in this city, flee to another. For assuredly, I say to you, you will not have gone through the cities of Israel before the Son of Man comes.
24 “A disciple is not above his teacher, nor a servant above his master.
Remember, also, that the Jews, for the most part, believed that the Messiah would be a conqueror. Not a suffering servant. Thus, they expected war. A rebellion against the world, where they might be conscripted into service.
Rather, you should wonder at how marvelously God foresaw every little detail of our salvation. It amazes me, that many centuries before it happened, someone described the Crucifixion in detail.
**Wisdom 2:12
- Let us lie in wait for the righteous one, because he is annoying to us;
he opposes our actions,
Reproaches us for transgressions of the law*
and charges us with violations of our training.g
13
He professes to have knowledge of God
and styles himself a child of the LORD.h
14
To us he is the censure of our thoughts;
merely to see him is a hardship for us,i
15
Because his life is not like that of others,
and different are his ways.
16
He judges us debased;
he holds aloof from our paths as from things impure.
He calls blest the destiny of the righteous
and boasts that God is his Father.j
17
Let us see whether his words be true;
let us find out what will happen to him in the end.k
18
For if the righteous one is the son of God, God will help him
and deliver him from the hand of his foes.l
19
With violence and torture let us put him to the test
that we may have proof of his gentleness
and try his patience.
20
Let us condemn him to a shameful death;
for according to his own words, God will take care of him.”m
21
These were their thoughts, but they erred;
for their wickedness blinded them,n
22
- And they did not know the hidden counsels of God;
neither did they count on a recompense for holiness
nor discern the innocent souls’ reward.o
23
For God formed us to be imperishable;
the image of his own nature he made us.p
24
But by the envy* of the devil, death entered the world,
and they who are allied with him experience it.q**
