'Forsake' in the Bible

“As for you, Solomon my son, know the God of your father [have personal knowledge of Him, be acquainted with, and understand Him; appreciate, heed, and cherish Him] and serve Him with a blameless heart and a willing mind; for the Lord searches all hearts and minds, and understands every intent and inclination of the thoughts. If you seek Him [inquiring for and of Him and requiring Him as your first and vital necessity] He will let you find Him; but if you abandon (turn away from) Him, He will reject you forever.

Then David said to his son Solomon, “Be strong and courageous, and take action; do not fear nor be dismayed, for the Lord God, my God, is with you. He will not fail you nor abandon you [but will guide you in the construction] until you have finished all the work for the service of the house of the Lord.
