Nefesh HaChayim, Reb Itzele's Long Annotation

But the choice was his, and the d’moot was in potential and not yet active. For that reason it is written “Let us make man with our tzellem and per our d’moot505Heb.: ki’d’moo-teinoo”, using the kaf-of-similarity506Heb.: kaf ha-dim-yone—When the letter kaf with a cheereek vowel is added at the beginning of a word, it adds a sense that the word that follows is like something else. It’s used that way here in relation to d’moot.. And for that reason, later it’s written: “God-Elohi”m created the man with His tzellem; with the tzellem of God-Elohi”m He created him”, and d’moot is not mentioned.
