John Lightfoot on Luke 18:31

[He took unto him the twelve.] This falls in with that of John 11:7, "Let us go into Judea." What! say they, into Judea again, where thou wast lately in so much danger? However, he comes out and goes on, his disciples following him wondering, and fearing the effects of it, Mark 10:32. He mentioned only at present his journey into Judea, to see Lazarus: but, as they were going, he foretells his progress to Jerusalem, and what was to be done with him there. It is probable he was at Bethabarah when the message came to him that Lazarus was sick; and from thence, his way lying conveniently over the Scythopolitan bridge, and so through part of Samaria, he chooseth the transjordanine way to the fords of Jericho.
