Mark 8:10-12

¹⁰And immediately He entered the boat with His disciples and came to the district of Dalmanutha.

¹¹ The Pharisees came out and began to argue with Him, seeking from Him a sign from heaven, to test Him. ¹²Sighing deeply in His spirit, He said, “Why does this generation seek for a sign? Truly I say to you, no sign will be given to this generation.”
