2 Corinthians 12:3

the rapture of the Apostle Paul even into the third heaven, that is, to a third of the distance of the height of heaven from the earth—namely, as far as the firmament; then his rapture into Paradise where he was privileged to be the hearer …

He therefore sets forth from these things for us two causes [of the visions], one pointing to labour, and the other to reward. For what does he say? I know a man in Christ fourteen years ago (whether in the body I know not, or …

Lest therefore you should be led into error when you hear that the blessed Paul had been caught up into the third heaven, I must point out that there are not three or more heavens, and that he neither means to say this, nor contradicts …

Great indeed was this revelation. But this was not the only one: there were many others besides, but he mentions one out of many. For that there were many, hear what he says: "Lest I should be exalted overmuch through the exceeding greatness of the revelations." 'And yet,' a man may say, 'if he wished to conceal them, he ought not to have given any intimation whatever or said any thing of the sort; but if he wished to speak of them, to speak plainly.' Wherefore then is it that he neither spoke plainly nor kept silence? To show by this also that he resorts to the thing unwillingly. And therefore also he has stated the time, "fourteen years." For he does not mention it without an object, but to show that he who had refrained for so long a time would not now have spoken out, except the necessity for doing so had been great. But he would have still kept silence, had he not seen the brethren perishing. Now if Paul from the very beginning was such an one as to be counted worthy of such a revelation, when as yet he had not wrought such good works; consider what he must have grown to in fourteen years. And observe how even in this very matter he shows modesty, by his saying some things, but confessing that of others he is ignorant. For that he was caught up indeed, he declared, but whether "in the body" or "out of the body" he says he does not know. And yet it would have been quite enough, if he had told of his being caught up and had been silent [about the other]; but as it is, in his modesty he adds this also. What then? Was it the mind that was caught up and the soul, whilst the body remained dead? or was the body caught up? It is impossible to tell. For if Paul who was caught up and whom things unspeakable, so many and so great, had befallen was in ignorance, much more we. […]

Paul says that he was caught up twice—first into the third heaven and then into paradise, which is where the Lord said that the thief on the cross would be with him..
