The answer is that the Old Testament says the Messiah would be called the "branch" without specifying one or more reasons why. Matthew 2:22 does not restrict Jesus from also being God’s "branch" from which His church would grow.
J: Si hivyo kabisa. Agano la Kale linasema Masihi ataitwa "tawi" bila kubainisha sababu yoyote ya kufanya hivyo. Mat 2:22 haimzuii Yesu kuwa "tawi" la Mungu pia ambalo kutoka kwake kanisa lingekua.
