'Separated' in the Bible

For until certain persons came from James he had been accustomed to eat with Gentiles; but as soon as these persons came, he withdrew and separated himself for fear of the Circumcision party.

But we, brethren, having been for a short time separated from you in bodily presence, though not in heart, endeavoured all the more earnestly, with intense longing, to see you face to face.

so the Christ also, having been once offered in sacrifice in order that He might bear the sins of many, will appear a second time, separated from sin, to those who are eagerly expecting Him, to make their salvation complete.
