סְמוּכִ֣ים לָעַ֣ד לְעוֹלָ֑ם עֲ֝שׂוּיִ֗ם בֶּאֱמֶ֥ת וְיָשָֽׁר׃
Ils sont inébranlables pour toute l’éternité, marqués au coin de la vérité et de la droiture.
Sefat Emet
"Made in truth and equity" (Ps. 111:8). It seems that we can understand that this verse applies to a person who does a mitzvah that can only be done in truth. Meaning, a person who is truth and equitable in those character traits are made [by them] and this is why the expression "made" is better.
