Dost thou yet hold back my people: and wilt thou not let them go?
As yet exaltest thou thyself against my people, that thou wilt not let them go?
Since you are still exalting yourself [in haughty defiance] against My people by not letting them go,
You are still abusing your power against my people, and you refuse to let them go.
Do you still retain my people, and are you still unwilling to release them?
