'Separate' in the Bible

three cities thou dost separate for thee in the midst of thy land which Jehovah thy God is giving to thee to possess it.

therefore I am commanding thee, saying, Three cities thou dost separate to thee.

And by precious things -- of earth and its fulness, And the good pleasure Of Him who is dwelling in the bush, -- Let it come for the head of Joseph, And for the crown of him Who is separate from his brethren.
