[3:164] GOD has blessed the believers by raising in their midst a messenger from among them, to recite for them His revelations, and to purify them, and to teach them the scripture and wisdom. Before this, they had gone totally astray.
According to 3:164 the messenger has three purposes
- Recite the revelations of God
- Purify them (the revelations, the people, or the people’s belief?)
- Teach us the scripture and wisdom
God’s Messenger of the Covenant
[5:19] O people of the scripture, our messenger has come to you, to explain things to you, after a period of time without messengers, lest you say, “We did not receive any preacher or warner.” A preacher and warner has now come to you. GOD is Omnipotent.*
[2:151] (Blessings) such as the sending of a messenger from among you to recite our revelations to you, purify you, teach you the scripture and wisdom, and to teach you what you never knew.
