'Whomsoever' in the Bible

and I did not know him, but he who sent me to baptize with water, He said to me, On whomsoever thou mayest see the Spirit coming down, and remaining on him, this is he who is baptizing with the Holy Spirit;

verily, verily, I say to you, he who is receiving whomsoever I may send, doth receive me; and he who is receiving me, doth receive Him who sent me.'
