Once you have made a conclusion based on error, all other extrapolated conclusions are also wrong.
We are currently under the law of Christ (1 Cor 9:21) not the Mosaic laws (Rom 7:6). This means we are not to obey the former ceremonial laws but we are all held to the moral laws of God.
And your conclusion is that ...

is referring to Moses? My suggestion is that you go back and reread your statement about a conclusion based on error.
As far as who this is speaking the Ten Commandments...
1Co 10:1 Moreover, brethren, I would not that ye should be ignorant, how that all our fathers were under the cloud, and all passed through the sea;
1Co 10:2 And were all baptized unto Moses in the cloud and in the sea;
1Co 10:3 And did all eat the same spiritual meat;
1Co 10:4 And did all drink the same spiritual drink: for they drank of that spiritual Rock that followed them:
and that Rock was Christ.
I am pretty sure you don't know what you are talking about.
