Matthew 4:11

‘Then the devil leaves him, and behold, angels came and were ministering to him.'

And then in obedience to Jesus' dismissal Satan left him (for a while) and angels came and ministered to Him. How they ministered we are not told. Perhaps the imperfect tense ‘were ministering' informs us that their ministry had been withdrawn for a while so that Jesus had had to face Satan alone (something we never have to do), but that now they had returned again to provide their continual assistance. But they clearly now provided what was necessary for Him to recover from His ordeal. Ironically this fulfilled the promises in Psalms 91:11. The promises did apply for those who were faithful to God. However, not as something to be tested out facetiously. We are reminded here also of how Elijah was similarly sustained by God in the wilderness (1 Kings 19:5). Whether this time in the case of Jesus it was also with food we are not told. But whatever it was His Father met Him at the point of His need, as He always does.
