'Successful' in the Bible

Persist in trusting your amulets and your many incantations, which you have faithfully recited since your youth! Maybe you will be successful -- maybe you will scare away disaster.

I Yes, I! have spoken; indeed, I've called and I've brought him, and he will make his path successful.

so shall be my word that goes out from my mouth. It shall not return to me without success, but shall accomplish what I desire and be successful [in the thing for] which I sent it.
