Luke 13:18-19 Then said he, Unto what is the kingdom of God like? and whereunto shall I resemble it? It is like a grain of mustard seed, which a man took, and cast into his garden; and it grew, and waxed a great tree; and the fowls of the air lodged in the branches of it.
Ezekiel 17:22-23 Thus saith the Lord GOD; I will also take of the highest branch of the high cedar, and will set it; I will crop off from the top of his young twigs a tender one, and will plant it upon an high mountain and eminent: In the mountain of the height of Israel will I plant it: and it shall bring forth boughs, and bear fruit, and be a goodly cedar: and under it shall dwell all fowl of every wing; in the shadow of the branches thereof shall they dwell.
Remember the song "he is the vine and we are the branches"? Luke, Matthew, and Ezekiel can all be paralleled. Luke and Matthew are descriptive, and Ezekiel gives even more detail on what it is talking about, which is God's fulfillment of his promise for a Messiah (the highest branch that is taken and planted in Israel), and in the shadow of his wings (ok, branches, lol) all of the nations will take refuge and dwell in his presence.
