The words "he" and "his" speak of Jacob (verse 22) and represent his descendants. Alternate translation: "Jacob's descendants will no longer ... their faces ... they see their children" (See: [[rc://en/ta/man/translate/figs-metonymy]])
Here "hands" represents Yahweh's power and action. Alternate translation: "When they see all the children I have given them and all that I have done" (See: [[rc://en/ta/man/translate/figs-metonymy]])
Here "name" represents Yahweh. Yahweh refers to himself as "the Holy One of Jacob." Alternate translation: "They will honor me, the Holy One of Jacob" (See: [[rc://en/ta/man/translate/figs-metonymy]] and [[rc://en/ta/man/translate/figs-123person]])
