'Afar' in the Bible

Why standest thou afar off, O LORD? why hidest thou thyself in times of trouble?

My lovers and my friends stand aloof from my sore; and my kinsmen stand afar off.

Behold, I would flee afar off, I would lodge in the wilderness; Selah;

By terrible things in righteousness wilt thou answer us, O God of our salvation; who art the confidence of all the ends of the earth, and of them that are afar off upon the sea:

Though the LORD be high, yet hath he respect unto the lowly: but the proud he knoweth afar off.

Thou knowest my downsitting and mine uprising, thou understandest my thought afar off.
