Exodus 11

1 Either God was speaking to Moses while he was still in Pharaoh's presence or He had spoken to Moses earlier.
2 It is difficult to frame the context of these "gifts." They could have been parting gifts or bribery (i.e., please leave) gifts. These gifts can serve two purposes. First, it would provide "back pay" for the years of slavery that the people would endure. Secondly, it would provide the raw materials that would later be used to make the ark, tabernacle, and other items used in the worship of God.
3 The Egyptians feared and respected Moses because he apparently wielded the power to cause these miracles. However, few, if any, of the Egyptians feared or respected God to the point of obedience.
4 Moses is still speaking to Pharaoh.
5 God does not play favorites on the basis of wealth or power. When judgement comes, it will affect all the disobedient.

it is not specified in this verse, but Exo 13:15 might be interpreted to indicate that is was the firstborn males that were killed. However, while the Hebrew word here is often applied to the males (Strong's concordance) it does not appear to directly mean that. Thus, this plague could have applied to all the firstborn, whether they were male or female.

In the previous plagues, God works through secondary means. Pharaoh, and Bible critics since, has attempted to make these miracles into "coincidence" or play down the extent of the plague. However, in this last plague, God Himself would visit and judge the Egyptians. This miracle was predicted very specifically and there can be no doubt that it was indeed God that performed it.

6 There have been many large-scale tragedies throughout man's history. However, there has never been one that has struck every family in an entire nation.
7 This difference between Egypt and Israel can be considered one of obedience.

The Israelite's final night in Egypt would be a peaceful one.

Apparently the Israelites had dogs. Later, dogs would be deemed as "unclean," and even later, it would be a high insult to call someone a dog. However, neither of these would necessarily prohibit the use of domesticated dogs for such tasks as shepherding.

8 Moses finally leaves Pharaoh, and will never see him again (Exo 10:29). Moses is undoubtedly angry with Pharaoh for his stubborn refusal to acknowledge God, especially after the great miracles that were performed. Moses is sharing God's anger. But this time, Moses would stand back and let God judge the Egyptians rather than judging them himself (Exo 2:11,12).
