Matthew 10:41

Receiveth a prophet. That is, receives a prophet into his home and treats him as a prophet.

In the name of a prophet. That is, because he is a prophet, or is recognized as a prophet. The widow of Zarephath undoubtedly received Elijah as a prophet, because he was a prophet; otherwise she would likely have refused to extend to him the hospitality he requested of her (see 1 Kings 17:9-16). The same was true of the Shunammite woman, who received Elisha into her home (2 Kings 4:8-10).

A prophet’s reward. Probably meaning a reward worthy to be bestowed by a prophet or upon one. The widow of Zarephath received an ample supply of food in the midst of a drought, and her son was restored to life (see 1 Kings 17:16, 23). Similarly, the Shunammite woman received a bountiful reward, having been granted a son by God, and having received him back alive when he died (see 2 Kings 4:16, 17, 34-37).
