'Acknowledge' in the Bible

Instead he shall acknowledge the son of the unloved as the firstborn, by giving him a double portion of all that he has, for he was the beginning of his strength (generative power); to him belongs the right of the firstborn.

Who said of his father and mother,‘I did not consider them’;Nor did he acknowledge his brothers,Nor did he regard his own sons,For the priests observed Your word,And kept Your covenant.
