“… you shall not listen to the words of that [false] prophet or that dreamer of dreams. For the Lord your God is testing you, to know whether you love the Lord your God with all your heart and with all your soul. You shall walk after the Lord your God and fear him and keep his commandments and obey his voice, and you shall serve him and hold fast to him.” — Deuteronomy 13:3-4, ESV
“Behold, I am sending you out like sheep in the midst of wolves; be wary and wise as serpents, and be innocent (harmless, guileless, and without falsity) as doves.” — Matthew 10:16, The Amplified Bible
