Hebrews 5:11

Of whom we have many things to say, and hard to be uttered, seeing ye are dull of hearing.

About him we have many words to say, and hard to interpret, seeing you have become dull of hearing.

Of whom we have many things to say, and hard of interpretation, seeing ye are become dull of hearing.

concerning whom we have much discourse and of hard explanation to say, since ye have become dull of hearing,

We have much to say about this, but it is hard to explain, because you are dull of hearing.
