Native English speakers, could you please help me with these issues?

Can the verb 'to assist' ever have the meaning of 'to watch'? For instance, would it make to say: a) "Did you assist to the birth of your son?" b) "I assisted to the play "The swan lake." c) "On your first day of work, you will assisted by a superior." Note:... show more Can the verb 'to assist' ever have the meaning of 'to watch'?

For instance, would it make to say:


a) "Did you assist to the birth of your son?"

b) "I assisted to the play "The swan lake."

c) "On your first day of work, you will assisted by a superior."


Note: I remember that in all cases, I wonder if the verb 'to assist' has the same meaning as 'to watch'.
