'Heed' in the Bible

And did he not make one, although he had the residue of the Spirit? And wherefore one? He sought a godly seed. Therefore take heed to your spirit, and let none deal treacherously against the wife of his youth.

For I hate putting away, saith Jehovah, the God of Israel, and him that covereth his garment with violence, saith Jehovah of hosts: therefore take heed to your spirit, that ye deal not treacherously.
