'Art' in the Bible

My son, if thou art become surety for thy neighbor, If thou hast stricken thy hands for a stranger;

Thou art snared with the words of thy mouth, Thou art taken with the words of thy mouth.

Do this now, my son, and deliver thyself, Seeing thou art come into the hand of thy neighbor: Go, humble thyself, and importune thy neighbor;

Say unto wisdom, Thou art my sister; And call understanding thy kinswoman:

If thou art wise, thou art wise for thyself; And if thou scoffest, thou alone shalt bear it.

He that saith unto the wicked, Thou art righteous; Peoples shall curse him, nations shall abhor him:
