'Separation' in the Bible

All the days of his separation he shall not eat anything that is produced by the grape vine, from the seeds even to the skin.

‘All the days of his vow of separation no razor shall pass over his head. He shall be holy until the days are fulfilled for which he separated himself to the Lord; he shall let the locks of hair on his head grow long.

‘All the days of his separation to the Lord he shall not go near to a dead person.

He shall not make himself unclean for his father or for his mother, for his brother or for his sister, when they die, because his separation to God is on his head.

All the days of his separation he is holy to the Lord.

and shall dedicate to the Lord his days as a Nazirite, and shall bring a male lamb a year old for a guilt offering; but the former days will be void because his separation was defiled.

‘Now this is the law of the Nazirite when the days of his separation are fulfilled, he shall bring the offering to the doorway of the tent of meeting.

“This is the law of the Nazirite who vows his offering to the Lord according to his separation, in addition to what else he can afford; according to his vow which he takes, so he shall do according to the law of his separation.”

But your iniquities have made a separation between you and your God,And your sins have hidden His face from you so that He does not hear.
