I’m not sure evidence would support this but would it be possible that these are the two?
Mat 17:3 And, behold, there appeared unto them Moses and Elias talking with him.
Mat 17:4 Then answered Peter, and said unto Jesus, Lord, it is good for us to be here: if thou wilt, let us make here three tabernacles; one for thee, and one for Moses, and one for Elias.
A few chapters later we read…..
Mat 20:21 And he said unto her, What wilt thou? She saith unto him, Grant that these my two sons may sit, the one on thy right hand, and the other on the left, in thy kingdom.
Mat 20:22 But Jesus answered and said, Ye know not what ye ask. Are ye able to drink of the cup that I shall drink of, and to be baptized with the baptism that I am baptized with? They say unto him, We are able.
Mat 20:23 And he saith unto them, Ye shall drink indeed of my cup, and be baptized with the baptism that I am baptized with: but to sit on my right hand, and on my left, is not mine to give, but it shall be given to them for whom it is prepared of my Father.
But to sit on my right hand, and on my left, is not mine, to give; in the sense in which they asked it, since he was no temporal prince; nor was his kingdom of this world; nor had he any such external favours, or worldly honours:
and as to the true and spiritual sense of such a phrase, it was not a point to be fixed now by him, as man, and according to his own will; as who should reign with him in the kingdom of heaven, who should sit down on the same throne with him, and enjoy all the glories and happiness of the world to come; and though, as mediator, all this glory was given to him, and he had it in his hands to give to others, yet to none
for whom, says he,
it is prepared of my Father: for this is the true reading and sense of the last clause; signifying, that eternal life, or the heavenly glory, is a kingdom prepared by his Father, from the foundation of the world, and not for anybody, and every person, but for some only, according to his Father’s sovereign will and pleasure;
and that this is an affair that was fixed by him, in his eternal counsels and purposes, and in the covenant of his grace, and not to be adjusted now; nor was the designation of it to be, nor will the distribution of it be according to the merits of men, but the free grace of God; and though he, as mediator, was appointed to bestow both grace and glory on men,
yet only on those the Father had given to him, for whom grace was laid up in him, and glory prepared.
(2.) He leaves them in the dark about the degrees of their glory. To carry them cheerfully through their sufferings, it was enough to be assured that they should have a place in his kingdom. The lowest seat in heaven is an abundant recompence for the greatest sufferings on earth. But as to the preferments there, it was not fit there should be any intimation given for whom they were intended; for the infirmity of their present state could not bear such a discovery with any evenness; “To sit on my right hand and on my left is not mine to give, and therefore it is not for you to ask it or to know it; but it shall be given to them for whom it is prepared of my Father.” Note, [1.] It is very probable that there are degrees of glory in heaven; for our Saviour seems to allow that there are some that shall sit on his right hand and on his left, in the highest places. [2.] As the future glory itself, so the degrees of it, are purposed and prepared in the eternal counsel of God; as the common salvation, so the more peculiar honours, are appointed, the whole affair is long since settled, and there is a certain measure of the stature, both in grace and glory, Eph 4:13. [3.] Christ, in dispensing the fruits of his own purchase, goes exactly by the measures of his Father’s purpose; It is not mine to give, save to them (so it may be read) for whom it is prepared. Christ has the sole power of giving eternal life, but then it is to as many as were given him, Joh 17:2. It is not mine to give, that is, to promisenow; that matter is already settled and concerted, and the Father and Son understand one another perfectly well in this matter. “It is not mine to give to those that seek and are ambitious of it, but to those that by great humility and self-denial are prepared for it.”
