Trouble was predicted by The Load

Exodus 5:1-23
Ever since I went to Pharaoh to speak in your name, he has brought trouble upon this people.
Pharaoh did not know The Load and was not let Israel go, and said they are lazy.
Pharaoh laid more heavy labor on Israelite.
The Israelite foreman appealed to Pharaoh , and realized they were in trouble. After that they complained with Moses and Aaron.
Why?
When told someone who do not know The Load, may get more worse feed back.
This seems less than the whole truth; but it is in the nature of a testcase. Israel had to leave Egypt in order to sacrifice because the nature of their sacrifice was offensive to the Egyptians.
Pharaoh reaction reveals his implacable hostility, already predicted by God.
Pharaoh do know The Load so criticized Israelite lazy.
How?
We do follow the command of God, do in name of God, sometime may get more trouble. But this is the procedure, that God is with us. Do not afraid of it, it is in the hand of God.
Do not talk to much about the Load with who doesn't knows God.
Trouble does not mean God did it, but it was predicted by God.
