Charles Ellicott Commentary Psalms 22:30

"A seed shall serve him; It shall be told of the Lord unto the [next] generation." — Psalms 22:30 (ASV)

A seed ... — Better, Posterity shall serve Him. About Jehovah it shall be told to the (coming) generation. The article supports this interpretation. Others, as in Psalms 87:6, understand a reference to the census; but the parallelism is against this reference. The next verse repeats the same thought in another form.
