'Locks' in the Bible

‘All the time of the vow of his separation no razor shall be used on his head. Until the time of his separation to the Lord is completed, he shall be holy, and shall let the hair of his head grow long.

“His head is like [precious] gold, pure gold;His hair is [curly] like clusters of datesAnd black as a raven.

Also they shall not shave their heads, yet they shall not allow their hair to grow long; they shall only cut short or trim their hair.
