Omniscient (all knowing): Esther 14:14 (chapter not in Protestant bible); 1 Cor 2:10; Ecclesiasticus/Sirach 23:29 Douay; 23:19-20 RSV-CE (book not in Protestant bible); Ps 138:3-5 Douay

Impassive: ?? Do you mean that God is not subject to physical laws of occupied space?? (as Our Lord’s risen body was said to be impassible - that is, it could pass through walls.)
