'Forsake Not' in the Bible

Take heed to thyself that thou forsake not the Levite as long as thou livest upon the earth.

The LORD will perfect that which concerneth me: thy mercy, O LORD, endureth for ever: forsake not the works of thine own hands.

My son, hear the instruction of thy father, and forsake not the law of thy mother:

My son, keep thy father's commandment, and forsake not the law of thy mother:

Thine own friend, and thy father's friend, forsake not; neither go into thy brother's house in the day of thy calamity: for better is a neighbour that is near than a brother far off.
