Psalms 105:31

He spake, and there came divers sorts of flies, and lice in all their coasts.

He spoke, and swarms of flies and lice came upon Egypt. This was one of the judgments that struck the land at the time of the Exodus. The verse belongs to the record of Israel's experience given in Psalm 105 and continued in Psalm 106.

That experience was that all were under the cloud and passed through the sea and were baptized unto Moses in the cloud and in the sea, and all ate the same spiritual meat and drank the same spiritual drink from the spiritual Rock that followed them, which was Christ, yet many were overthrown in the wilderness because God was not well pleased with them. The record is a warning lesson that God's people in the last days especially need to study. Psalms 105 and 106 should be read at least once every week.
