7 “Now Jesus loved Martha, and her sister Mary, and Lazarus.” The one sick, the others sad, all of them beloved: but He who loved them was both the Saviour of the sick, nay more, the Raiser of the dead and the Comforter of the sad. “When He heard therefore that he was sick, He abode then two days still in the same place.” They sent Him word: He abode where He was: and the time ran on till four days were completed. And not in vain, were it only that perhaps, nay that certainly, even the very number of days has some sacramental significance. “Then after that He says again to His disciples, Let us go into Judea:” where He had been all but stoned, and from which He had apparently departed for the very purpose to escape being stoned. For as man He departed; but returned as if in forgetfulness of all infirmity, to show His power. “Let us go,” He said, “into Judea.”
