'Forsake Not' in the Bible

Take heed to yourself that you forsake not the Levite as long as you live upon the earth.

The LORD will perfect that which concerns me: your mercy, O LORD, endures forever: forsake not the works of your own hands.

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

For I give you good doctrine, forsake not my law.

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

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