And Jesus said unto him, Foxes have holes, and birds of the air [have] nests; but the Son of man hath not where to lay [his] head.
Note 1 at Lu 9:58: This verse has often been used to support the misconception that Jesus and His disciples lived in poverty. However, in this instance, the fact that Jesus had nowhere to lay His head was because of persecution. The Samaritans, because of a religious prejudice (see note 1 at Lu 9:53), had just refused Him hospitality and a place to stay as He journeyed to Jerusalem. Persecution is a part of the cost of living a Christian life (see note 7 at Mt 5:10), and Jesus was communicating to this man that not having a place to stay at times was part of that cost.
The Scriptures record Jesus as being a guest in other peoples' homes often, and Joh 1:38-39 even records Jesus inviting two disciples to dwell with Him.
Lu 8:3 relates how Joanna, Susanna, and "many others" ministered to Jesus of their "substance" (Greek - "HUPARCHONTA"--"property or possessions" [Strong's Concordance]). Jesus and His disciples were also in a position where they gave to the poor out of their funds (Joh 12:5 and 13:29).
From these examples and many others (see note 36 at Mt 6:19, note 37 at Mt 6:20, and note 38 at Mt 6:21), it is clear that Jesus' statement in this verse related to persecution and not to poverty. Not until Jesus suffered and died on the cross did He take on the curse of poverty (De 28:17 with Ga 3:13) so that we might be made rich (2Co 8:9 with Ga 3:14). See note 2 at Lu 9:23.
