It is an appearance of the Lord Jesus Christ.
We see many of these in the Old Testament. Yes, I said the Old Testament.
I believe I can show you an example.
Please read the following verses and see Christ.
1 This Melchizedek was king of Salem and priest of God Most High. He met Abraham returning from the defeat of the kings and blessed him, 2 and Abraham gave him a tenth of everything. First, his name means “king of righteousness”; then also, “king of Salem” means “king of peace.”
3 Without father or mother, without genealogy, without beginning of days or end of life, like the Son of God, he remains a priest forever.
4 Just think how great he was: Even the patriarch Abraham gave him a tenth of the plunder!
5 Now the law requires the descendants of Levi who become priests to collect a tenth from the people — that is, their brothers — even though their brothers are descended from Abraham.
6 This man, however, did not trace his descent from Levi, yet he collected a tenth from Abraham and blessed him who had the promises.
7 And without doubt, the lesser person is blessed by the greater.
8 In the one case, the tenth is collected by men who die; but in the other case, by him who is declared to be living.
9 One might even say that Levi, who collects the tenth, paid the tenth through Abraham, 10 because when Melchizedek met Abraham, Levi was still in the body of his ancestor.
