'Opening' in the Bible

And Philip, opening his mouth and beginning from that scripture, announced the glad tidings of Jesus to him.

And Peter opening his mouth said, Of a truth I perceive that God is no respecter of persons,

opening and laying down that the Christ must have suffered and risen up from among the dead, and that this is the Christ, Jesus whom I announce to you.

and for me in order that utterance may be given to me in the opening of my mouth to make known with boldness the mystery of the glad tidings,

Does the fountain, out of the same opening, pour forth sweet and bitter?
