'Acknowledge' in the Bible

He must acknowledge the firstborn, the son of the unloved wife, by giving him two shares of his estate, for he is the firstfruits of his virility; he has the rights of the firstborn.

When you come before the priest who is serving at that time, you must say to him, ‘Today I acknowledge to the Lord your God that I have entered the land the Lord swore to our fathers to give us.’

He said about his father and mother,“I do not regard them.”He disregarded his brothersand didn’t acknowledge his sons,for they kept Your wordand maintained Your covenant.
