Perfect, a yearling, male
it is reasonably counted toward a sheep. "A perfect male yearling" sheep. For Christ is perfect in that he lacks in nothing and has nothing incomplete through himself. Male makes clear what is firm and manly in him. And it has been called a yearling since the year signifies a completed number, the sun being restored to its own place through twelve months.
