John 14:25-27 New Revised Standard Version (NRSV)
25 “I have said these things to you while I am still with you. 26 But the Advocate,[a] the Holy Spirit, whom the Father will send in my name, will teach you everything, and remind you of all that I have said to you. 27 Peace I leave with you; my peace I give to you. I do not give to you as the world gives. Do not let your hearts be troubled, and do not let them be afraid.
