to receive power - Greek, “the power.” The remaining six (the whole being seven, the number for perfection and completeness) are all, as well as “power,” ranged under the one Greek article, to mark that they form one complete aggregate belonging to God and His co-equal, the Lamb. Compare Rev 7:12, where each of all seven has the article.
riches - both spiritual and earthly.
blessing - ascribed praise: the will on the creature’s part, though unaccompanied by the power, to return blessing for blessing conferred [Alford].
