These are very blessed things spoken of, both as they relate to Christ, and to his people in him. Jesus in his human nature, uniformly made Jehovah his portion, and looked unto him to maintain his cause, and carry him safely through his vast undertaking. He not only considered it his meat and his drink to do his Father's will, but his redeemed he considered a goodly heritage. And what is it to his people but the same? They who have chosen God for their portion, find that portion to be a goodly one, and are fully satisfied with Jesus, for they need no other.
