I use the suggestion to try to use "Deities" to mean "Goddess and God." What do you think? I also added the wives of Jacob and the wife of Joseph. While I didn't have to change verse 12, I love it.
10 And I said, This is my infirmity: but I will remember the years of the right hand of the most High.
11 I will remember the works of the Lord and Lady: surely I will remember thy wonders of old.
12 I will meditate also of all thy work, and talk of thy doings.
13 Thy way, O Goddess and God, is in the sanctuary: who is so great Deities as our Gods?
14 Thou art the Goddess and God that doest wonders: thou hast declared thy strength among the people.
15 Thou hast with thine arm redeemed thy people, the children of Jacob and Leah and Rachel, and Asenath and Joseph. Selah.
