Not to attack or debate, but can you share with me the scriptures you are referencing? I cannot think of them, which is probably my fault since I have not gone through the entire NT for quite awhile.
Not off the top of my head. They’re all through the General Epistles (Timothy, Titus etc.). The OT passages are in Samuel and Kings where the stories of Elijah and Elisha are given. It’s clearest in the story about the axehead that swims after being dropped in the river.
Take any decent concordance and look for virgins, widows, schools + prophets.
The apostles attending daily Temple prayers is in Acts ch. 4.
