It is likely that Moses did not hide the signs that might have led them to such an understanding, and the severe oppression they endured under Pharaoh should have prompted them to anticipate divine intervention, making them alert to any significant events reflecting God’s favor toward them.
However, Moses was fearful and questioned why the matter had come to light. What was he afraid of? Perhaps he worried that the murder would become known among the Hebrews, but he desired just that, as he intended to demonstrate to them his divine election for their deliverance. While Moses wished to broadcast the significance of his action, he was disheartened by the negative perception held by his people. He recognized that their prolonged servitude had crushed their hope for liberation, rendering them distrustful of the one sent to lead them out, and potentially inclined to report him to the Egyptian authorities as a threat. This reaction from the Hebrews took him by surprise, instilling fear and astonishment in him at their unanticipated response. He lamented, "If this word be revealed," reflecting his distress that a divinely inspired act intended for the benefit of his fellow countrymen was misinterpreted and carelessly spread, potentially reaching the Egyptians. The term “verb” in the context of action is also found elsewhere in Scripture (Luke 2:15).
