I cannot give you the details of where they were, but here is an account of something that happened, and from what I understand this is no parable as Jesus used proper nouns
Luk 16:20 "And a poor man named Lazarus was laid at his gate, covered with sores,
Luk 16:21 and longing to be fed with the crumbs which were falling from the rich man's table; besides, even the dogs were coming and licking his sores.
Luk 16:22 "Now the poor man died and was carried away by the angels to Abraham's bosom; and the rich man also died and was buried.
Luk 16:23 "In Hades he lifted up his eyes, being in torment, and *saw Abraham far away and Lazarus in his bosom.
Luk 16:24 "And he cried out and said, 'Father Abraham, have mercy on me, and send Lazarus so that he may dip the tip of his finger in water and cool off my tongue, for I am in agony in this flame.'
Luk 16:25 "But Abraham said, 'Child, remember that during your life you received your good things, and likewise Lazarus bad things; but now he is being comforted here, and you are in agony.
Luk 16:26 'And besides all this, between us and you there is a great chasm fixed, so that those who wish to come over from here to you will not be able, and that none may cross over from there to us.'
Luk 16:27 "And he said, 'Then I beg you, father, that you send him to my father's house--
I also believe that Abaham and the prophets etc. had the gospel preached to them while on earth, I'm not saying that they understood it as we do but they believed. I know that they looked foward to the coming Messiah.
Luk 2:25 And there was a man in Jerusalem whose name was Simeon; and this man was righteous and devout, looking for the consolation of Israel; and the Holy Spirit was upon him.
Luk 2:26 And it had been revealed to him by the Holy Spirit that he would not see death before he had seen the Lord's Christ.
Notice how Simeon had been looking foward to the Lord's Christ
Gal 3:6 Even so Abraham BELIEVED GOD, AND IT WAS RECKONED TO HIM AS RIGHTEOUSNESS.
Gal 3:7 Therefore, be sure that it is those who are of faith who are sons of Abraham.
Gal 3:8 The Scripture, foreseeing that God would justify the Gentiles by faith, preached the gospel beforehand to Abraham, saying, "ALL THE NATIONS WILL BE BLESSED IN YOU."
I don't mean to take the scriptures out of context, but I think it can be concluded that Abraham believed the gospel
In you all the nations will be blessed
Gal 3:16 Now the promises were spoken to Abraham and to his seed. He does not say, "And to seeds," as referring to many, but rather to one, "And to your seed," that is, Christ.
Anyway thats my view thanks
