I am looking for a scripture or scriptures where it talks about the leadership role of the Apostles. I thought theres one that talks about that Apostles are suppose to be leaders apoint who the Pastors are.

This is probably not what you are looking for but I came across this:

Very briefly, the position of pastor/ teacher is outlined by Paul to be among the team of leaders in the church. They would work along side the apostles, prophets and evangelists "to equip the saints for the work of ministry, for building up the body of Christ, until all of us come to the unity of the faith and of the knowledge of the Son of God, to maturity, to the measure of the full stature of Christ." (Eph 4:12,13).
