How to Discerning the voice of El יהוה / Yahweh / יהושע / Yahshua ( LORD, GOD, Adonai)

But ye believe not,because ye are not of my sheep,as I said unto you.I am the good shepherd,and know my sheep,and am known of mine.My sheep hear my voice,and I know them, and they follow me. For my sheep know my voice,but they will flee from a stranger,for they know not the voice of strangers.
