Charles H. Spurgeon on Psalms 105:11

Your inheritance. The change of the number (from "thee" to "your") points out that God made a covenant with all the people in general, though lie spake the words only to a few individuals; even as we have seen a little before, that it was a decree or an everlasting law. The holy patriarchs were the first and principal persons into whose hands the promise was committed; but they did not embrace the grace which was offered to them as belonging only to themselves, but as a blessing which their posterity in common with them were to become sharers of. John Calvin.
