What does Exodus 4:19 mean?
Not every communication from God to Moses was as dramatic as the burning bush (Exodus 3:4–6) or the mountain of Sinai (Exodus 19:16–20). The Bible doesn't explain exactly how the Lord gave this information to Moses. It may have been in an audible voice, a mental communication, or something else. In any case, Moses won't be in immediate danger when he returns to Egypt.Moses went into exile after killing an abusive Egyptian taskmaster (Exodus 2:11–15). Other Scriptures explain that Moses left Egypt when he was about forty years old (Acts 7:23), and didn't return until he was eighty (Exodus 7:7). Apparently, anyone who knew enough—or cared enough—about the incident was dead. This might have reassured Moses or made him feel more comfortable in bringing along his family (Exodus 4:20).
