Isn’t that the number rule in our faith!1 Peter 1:16 English Standard Version since it is written, “You shall be holy, for I am holy.” let me throw down a couple translations 
King James BibleBecause it is written, Be ye holy; for I am holy. New King James Version because it is written, “Be holy, for I am holy.”
New American Standard Bible because it is written: “YOU SHALL BE HOLY, FOR I AM HOLY.” Contemporary English Version
That’s why the Scriptures say, “I am the holy God, and you must be holy too.”  I personally love the message bible for easy translation and breakdown for my students, 1 Peter 1:16 in The Message reads,   A Future in God ^13-16 So roll up your sleeves, get your head in the game, be totally ready to receive the gift that’s coming when Jesus arrives. Don’t lazily slip back into those old grooves of evil, doing just what you feel like doing. You didn’t know any better then; you do now. As obedient children, let yourselves be pulled into a way of life shaped by God’s life, a life energetic and blazing with holiness. God said, “I am holy; you be holy.” I mean come, here will the process starts! Amen
