And after this, he saith to his disciples. At length he now shows that he cared about Lazarus, though the disciples thought that he had forgotten him, or, at least, that there were other matters which he reckoned of more importance than the life of Lazarus. He therefore enjoins them to cross the Jordan, and go to Judea

Then after that,.... The next day, the third day after he had heard of Lazarus's sickness:
saith he to his disciples, let us go into Judea again; for the country beyond Jordan was distinguished from Judea; See Gill on Matthew 4:25.

Christ never brings his people into any danger but he goes with them in it. We are apt to think ourselves zealous for the Lord, when really we are only zealous for our wealth, credit, ease, and safety; we have therefore need to try our principles. But our day shall be lengthened out, till our work is done, and our testimony finished. A man has comfort and satisfaction while in the way of his duty, as set forth by the word of God, and determined by the providence of God. Christ, wherever he went, walked in the day; and so shall we, if we follow his steps. If a man walks in the way of his heart, and according to the course of this world, if he consults his own carnal reasonings more than the will and glory of God, he falls into temptations and snares. He stumbles, because there is no light in him; for light in us is to our moral actions, that which light about us to our natural actions.

Let us go into Judea again--He was now in Perea, "beyond Jordan."

Let us go into Judea - From the country east of Jordan, whither he had retired some time before, when the Jews sought to stone him, John 10:39-40.
