Acts 7:23-25

23And when a period of forty years was fulfilled to him, it came into his heart to look upon his brethren, the sons of Israel;

24and seeing a certain one wronged, he defended [him], and avenged him that was being oppressed, smiting the Egyptian.

25For he thought that his brethren would understand that 1God by his hand was giving them deliverance. But they understood not.
