Zechariah was in the temple burning incense when all of a sudden the angel Gabriel came to him. He told Zachariah that he was going to have a baby.
Zechariah was very doubtful and questioned the angel. For doubting a direct message from God Zechariah was speechless until the baby were to be born.
After five months of Elizabeth being pregnant she is very grateful to God that she can be having a baby at that age.
after six months of Elizabeth being pregnant the angel encounters Mary and tells her that she is going to be pregnant with the lord and she is to name him Jesus.
when Mary and Elizabeth see each other John jumps on the womb of his mother and she knew immediately that Mary was special.
Finally Elizabeth gives birth to his marvelous child and when they ask her what his name would be she said John and everybody questioned her because non of her relatives were named that way but Zechariah confirmed it and then he was able to talk again.
