15.16 have purchased... Nobody was really paid in the sense that the Lord bought them from Pharaoh. This is an interesting word.
15.24 grumbled... Verse 21 ended the song of praise and three verses later the grumbling starts. It doesn't take long to go from glorifying to grumbling.
16.2 grumbled against Moses and Aaron... goes on and on
16.7 grumbling... goes on and on
16.8 grumbling... goes on and on
16.9 grumbling... goes on and on

20.2 your God who brought you... They were obligated by his relationship and by what He had done for them. From slave
20.20 that the fear of the Lord may be before you... Not quite "God loves you and has a wonderful plan for your life." :o)
21.2 Hebrew slave... Nationality seems to have been a issue in most of these slave rules.
21.7 When a man sells his daughter... What's with that!? It seems strange to from my American perspective. "Verses 7-11 describe a girl whom her father sells as a servant (Heb. 'amah, v. 7) for marriage, not for slavery. (Kaiser, "Exodus," p. 430.)
