'Brother' in the Bible

Take ye heed every one of his neighbour, and trust ye not in any brother: for every brother will utterly supplant, and every neighbour will walk with slanders.

Therefore thus saith the LORD concerning Jehoiakim the son of Josiah king of Judah; They shall not lament for him, saying, Ah my brother! or, Ah sister! they shall not lament for him, saying, Ah lord! or, Ah his glory!

Thus shall ye say every one to his neighbour, and every one to his brother, What hath the LORD answered? and, What hath the LORD spoken?

And they shall teach no more every man his neighbour, and every man his brother, saying, Know the LORD: for they shall all know me, from the least of them unto the greatest of them, saith the LORD: for I will forgive their iniquity, and I will remember their sin no more.

That every man should let his manservant, and every man his maidservant, being an Hebrew or an Hebrewess, go free; that none should serve himself of them, to wit, of a Jew his brother.

At the end of seven years let ye go every man his brother an Hebrew, which hath been sold unto thee; and when he hath served thee six years, thou shalt let him go free from thee: but your fathers hearkened not unto me, neither inclined their ear.

Therefore thus saith the LORD; Ye have not hearkened unto me, in proclaiming liberty, every one to his brother, and every man to his neighbour: behold, I proclaim a liberty for you, saith the LORD, to the sword, to the pestilence, and to the famine; and I will make you to be removed into all the kingdoms of the earth.
