Acts 8:31

except some man[one] should[shall] guide me The eunuch, living far away from the received expounders of the Scriptures, feels that in a dark passage like that which he was reading he has need of trained instruction. He uses therefore the word which is employed for the guidance given by teacher to pupil. Our Lord uses it [Matthew 15:14; Luke 6:39] reproachfully of the blind guidance which the scribes and Pharisees in His day were giving to the people who came to them for instruction. He uses the same word for the guidance of the Holy Spirit (John 16:13). It was a marked feature in the teaching of the Jews that explanations of Scripture were received from generation to generation, and that only was highly valued by them which a man had received from his teachers. Such a system accounts for the permanence of all their traditions.

And he desired[besought] Philip that he would come up and sit with him The verb implies a very earnest request, and betokens the great desire which the eunuch had for more enlightenment.
