'Forsake' in the Bible

And thou, Solomon my son, know the God of thy father, and serve him with a perfect heart and with a willing mind; for Jehovah searches all hearts, and discerns all the imaginations of the thoughts. If thou seek him, he will be found of thee; but if thou forsake him, he will cut thee off for ever.

And David said to Solomon his son, Be strong and courageous, and do it; fear not nor be dismayed: for Jehovah Elohim, my God, will be with thee; he will not leave thee, neither forsake thee, until all the work for the service of the house of Jehovah is finished.
