A slave to who?
A slave to evil.
There are 3 indestructible questions here. The first I will answer – yes, Israel is a slave to evil like Cain was a slave to evil (Gen 4:7). Second question, ditto. Third question, this one I would adjust to read like this for our day: Why has he NOT become a prey? Do we not show ourselves as evil? What holds us back from causing any sort of resistance to genocide?
