Did you Know?

When Jesus cast out a demon(Luke 4:35-36), the people said he had power and authority. The Greek word translated as “authority” means freedom of choice and action. What they meant was that Jesus acted spontaneously, on his own, without permission.  Source: 1000 Bible Facts People, Places and Events

This is a very interesting article on how long the Plaques lasted.

How Long Did the Ten Plagues in Egypt Last?
The plagues probably took about 40 days, from Sunday, February 10 until Friday night, March 22, 1446 BC.
The Bible specifies how long some of the plagues lasted. For others, the Bible does not specify the length of time. Sometimes the Bible specifies a lapse of time between plagues; sometimes it does not. So, it is possible the total time span may have been a bit longer, but it could not have been very much shorter.
We can feel comfortable with a probable maximum time frame between February 1 and March 22, 1446 B.C. (the end date is certain – the 14th of Nisan in the Hebrew calendar, the First Passover).
Consider these terrible plagues falling like hammer blows within a space of 40 or 50 days upon the mighty nation of Egypt and leaving it in utter ruin and despair!
Deductions That Lead to the Time Frame of the Plagues
We find abundant time markers in the Bible. For many events, we can pinpoint the exact year, month, day, and sometimes hour. For others, we have to be content with a span of time, when events without time markers fall between other events that have time markers.
The key problem to Moses’ timeline is the date of the Exodus. The Bible does not give us the names of any of the Pharaohs – neither the one who knew Joseph, nor the one who “did not know Joseph” (Exodus 1:8, the one who ordered the male Israelite children thrown in the Nile, was probably Ahmose I), nor his successor (Exodus 2:23, the one who refused to let God’s people go and who suffered God’s plagues – probably Thutmose III.)
Another Pharaoh, probably Thutmose II, tried to kill Moses when Moses killed an Egyptian, and we know that after Moses fled to Midian (Arabia) to escape the death sentence, he stayed there 40 years (Acts 7:30).
1 Kings 6:1 tells that the time from the Exodus until Solomon’s fourth year as king (966 BC) was 480 years – pinpointing the Exodus at 966+480 = 1446 BC.
Assuming this is the right year (and there is some debate about that), the first Passover evening would be on the 14th of Nisan (the Hebrew month) or Friday, March 22, 1446 BC.
The sun set at 6:11 PM on that day. The angel of death passed through the homes of Egypt and killed all the male first born. On that night, Pharaoh summoned Moses and Aaron “Up and be gone…and bless me also!” (Exodus 12:31, 32)
The sun rose the next morning on Saturday, the Sabbath, March 23 at 5:59 AM. The Egyptians urgently sent the Israelites out of Egypt.
Were the Israelites breaking the Sabbath by traveling on that day? No. Although God rested on the Sabbath (“Sabbath” means “rest”) after creating the universe in six days, the command for the Israelites to observe the Sabbath only came later, with the first gathering of the manna (Exodus 16:5), and this happened after crossing the Red Sea into the vast wilderness of the Arabian peninsula.
So, if all this is correct, over what time did the plagues occur? Well, working backwards, the tenth plague (death of the first-born) occurred on Friday, March 22, 1446 BC. That is certain, because that is the 14th of Nisan, Passover Eve, 1446 BC.
It seems (but it is not certain) that the tenth plague happened the same night that the ninth plague (darkness) ended (Exodus 11:4). If so, since the ninth plague lasted three days (Exodus 10:23), then the ninth plague would have begun on Tuesday, March 16 and would have endured until Thursday, March 21, 1446 BC.
The eighth plague (locusts) consisted of one day and one night of an east wind (bringing the locusts), one day of a strong west wind (driving them into the Red Sea) and some period in the middle when the locusts devoured the plants of Egypt. We do not know how long the devouring endured. Let us say the whole plague took one week. If so, the eighth plague may have begun on Tuesday, March 12 and may have endured until Monday, March 18, 1446 B.C.
The seventh plague (hail) took two days: one day to threaten Pharaoh (Exodus 9:13) and the following day to send the hail (Exodus 9:18). It is not clear, whether there was a lapse between the seventh and eighth plagues, but if there was not, then the seventh plague began on Sunday, March 10 and endured until Monday, March 11, 1446 BC.
The sixth plague (boils) seems to have come right before the seventh plague (Exodus 9:13), but the Bible gives no clue how long it lasted. So, let us say it took a week. If so, it began on Sunday, March 3 and endured through Saturday, March 9, 1446 BC.
The fifth plague (death of livestock) seems to have occurred right before the sixth plague, and it took two days: one to threaten Pharaoh and one for God to kill the livestock. If so, it began on Friday, March 1 and endured through Saturday, March 2, 1446 BC.
The fourth plague (flies) endured for three days. The first day was to threaten Pharaoh (Exodus 8:20). The second day the flies came (Exodus 8:23), and the third day the flies dispersed (Exodus 8:29). So, this plague began on Tuesday, February 26 and ended on Thursday, February 28, 1446 B.C.
The Bible gives no clue how long the third plague (gnats) lasted. Since Pharaoh’s wizards tried to duplicate the miracle, let us say it lasted one more day than the fourth plague, thus four days. If so, it began on Friday, February 22 and ended Monday, February 25, 1446 BC.
The minimum time for the second plague (frogs) is two days: one day to threaten Pharaoh (Exodus 8:1), possibly the same day for the frogs to swarm (perhaps Pharaoh’s magicians imitated this on the same day), and one day for the frogs to die (Exodus 8:10). However, since the Egyptians piled up the rotting frogs in heaps and the land stank (Exodus 8:14), we should probably allow at least three days for this event to ripen. If so, the total plague took five days. And if so, it began on Sunday, February 17, 1446 BC.
The first plague (blood) took seven days after Moses struck the Nile, so eight days in all (Exodus 7:25).
If our timeline is accurate, the first plague began on Sunday, February 10 and the tenth plague ended on Friday, March 22, 1446 BC – a total of 40 days.
