Matthew 21:3 - Ellicott's Commentary On The Whole Bible

The Lord hath need of them. — Simple as the words are, they admit of three very different interpretations. “The Lord” may be used either (1) in the highest sense as equivalent to Jehovah, as though the ass and the colt were claimed for His service; or (2) as referring to Christ in the special sense in which He was spoken of as “the Lord” by His disciples; or (3) as pointing to Him, but only in the language which all men would acknowledge, and without any special claim beyond that of being the Master whom the disciples owned as in a lower sense their Lord. Of these (3) is all but excluded by the facts of the case. The words involve a claim to more than common authority, and the claim is recognised at once. In favour of (2) we have the numerous instances in which the disciples and the evangelists not only address their Master as “Lord,” but speak of Him as “the Lord” (Matthew 28:6; Mark 16:19; Luke 10:1; Luke 17:6; Luke 18:6; John 11:2; John 13:13; John 20:2; John 20:13; John 20:18; John 20:20; John 20:25; John 21:7; John 21:12). For (1), lastly, we have our Lord’s use of the word as a synonym for God (Mark 5:19; Mark 13:20). On the whole (2) appears to commend itself as most in accordance with the customary language of the disciples. On the very probable assumption that the owners of the colt were, in some sense, themselves disciples, they would recognise the full import of the words thus addressed to them, and obey without hesitation.
