See to it that you do not refuse Him who is speaking. For if those did not escape when they refused him who warned them on earth, much less will we escape who turn away from Him who warns from heaven.

Provoke him not

The Lord said to Moses, “How long will this people spurn Me? And how long will they not believe in Me, despite all the signs which I have performed in their midst?

How often they rebelled against Him in the wilderness
And grieved Him in the desert!

Do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption.

“Therefore I was angry with this generation,
And said, ‘They always go astray in their heart,
And they did not know My ways’;

He will not

I, the Lord, have spoken, surely this I will do to all this evil congregation who are gathered together against Me. In this wilderness they shall be destroyed, and there they will die.’”

“Why should I pardon you?
Your sons have forsaken Me
And sworn by those who are not gods.
When I had fed them to the full,
They committed adultery
And trooped to the harlot’s house.

As I swore in My wrath,

‘They shall not enter My rest.’”

For if we go on sinning willfully after receiving the knowledge of the truth, there no longer remains a sacrifice for sins,

If anyone sees his brother committing a sin not leading to death, he shall ask and God will for him give life to those who commit sin not leading to death. There is a sin leading to death; I do not say that he should make request for this.
