In my opinion, Paul was the one that the Lord chose.
Peter did cast lots; but I remember from reading Samuel.
The high priest had to do the choosing, method they went by.
While people may disagree with me; The Lord called Paul. He was very humbled by the Lord.
“Now the Lord said to Samuel, “How long are you going to mourn for Saul, since I have rejected him from being king over Israel? Fill your horn with oil and go; I will send you to Jesse the Bethlehemite, because I have chosen a king for Myself among his sons.” But Samuel said, “How can I go? When Saul hears about it, he will kill me.” But the Lord said, “Take a heifer with you and say, ‘I have come to sacrifice to the Lord.’ And you shall invite Jesse to the sacrifice, and I will let you know what you shall do; and you shall anoint for Me the one whom I designate to you.” So Samuel did what the Lord told him, and he came to Bethlehem. Then the elders of the city came trembling to meet him and said, “Do you come in peace?” And he said, “In peace; I have come to sacrifice to the Lord. Consecrate yourselves and come with me to the sacrifice.” He also consecrated Jesse and his sons and invited them to the sacrifice. When they entered, he looked at Eliab and thought, “Surely the Lord’s anointed is standing before Him.” But the Lord said to Samuel, “Do not look at his appearance or at the height of his stature, because I have rejected him; for God does not see as man sees, since man looks at the outward appearance, but the Lord looks at the heart.” Then Jesse called Abinadab and had him pass before Samuel. But he said, “The Lord has not chosen this one, either.” Next Jesse had Shammah pass by. And he said, “The Lord has not chosen this one, either.” So Jesse had seven of his sons pass before Samuel. But Samuel said to Jesse, “The Lord has not chosen these.” Then Samuel said to Jesse, “Are these all the boys?” And he said, “The youngest is still left, but behold, he is tending the sheep.” So Samuel said to Jesse, “Send word and bring him; for we will not take our places at the table until he comes here.””

“Now Saul, still breathing threats and murder against the disciples of the Lord, went to the high priest, and asked for letters from him to the synagogues in Damascus, so that if he found any belonging to the Way, whether men or women, he might bring them in shackles to Jerusalem. Now as he was traveling, it happened that he was approaching Damascus, and suddenly a light from heaven flashed around him; and he fell to the ground and heard a voice saying to him, “Saul, Saul, why are you persecuting Me?” And he said, “Who are You, Lord?” And He said, “I am Jesus whom you are persecuting, but get up and enter the city, and it will be told to you what you must do.””

“then He appeared to James, then to all the apostles; and last of all, as to one untimely born, He appeared to me also. For I am the least of the apostles, and not fit to be called an apostle, because I persecuted the church of God. But by the grace of God I am what I am, and His grace toward me did not prove vain; but I labored even more than all of them, yet not I, but the grace of God with me. Whether then it was I or they, so we preach and so you believed.”
1 Corinthians 15:7-11 NASB2020
But by the grace of God I am what I am, and His grace toward me did not prove vain; but I labored even more than all of them, yet not I, but the grace of God with me.

Apostle
one who is sent off
An apostle (/əˈpɒsəl/), in its literal sense, is an emissary. The word is derived from Ancient Greek ἀπόστολος (apóstolos), literally "
one who is sent off", itself derived from the verb ἀποστέλλειν (apostéllein), "to send off".
