'Forsake' in the Bible

You, Solomon my son, know the God of your father, and serve him with a perfect heart and with a willing mind; for Yahweh searches all hearts, and understands all the imaginations of the thoughts. If you seek him, he will be found by you; but if you forsake him, he will cast you off forever.

David said to Solomon his son, "Be strong and courageous, and do it. Don't be afraid, nor be dismayed; for Yahweh God, even my God, is with you. He will not fail you, nor forsake you, until all the work for the service of the house of Yahweh is finished.
