Charles Spurgeon Commentary Isaiah 61:8

"For I, Jehovah, love justice, I hate robbery with iniquity; and I will give them their recompense in truth, and I will make an everlasting covenant with them." — Isaiah 61:8 (ASV)

For I the LORD love judgment, I hate robbery for burnt offering; and I will direct their work in truth, and I will make an everlasting covenant with them.

That is why they have everlasting joy. There would be no everlasting joy if it were not for the everlasting covenant. Those gentlemen who want to cut that word "everlasting" out of our Bibles will find that it will be a very long time before we will agree to be deprived of it; no, we will never consent to give it up. We will always rejoice that we have God's everlasting love and an everlasting covenant, and therefore that we will have everlasting joy.
