Verses 20-21 state the punishment that Yahweh will send on such a person. It is described in vivid and repetitious detail. Moses is still the speaker.
The LORD would not pardon him: as long as he continues in his stubborn ways, he cannot be forgiven. Him refers to anyone who acts like this. So we may say “Yahweh will not pardon that person.” For a comment on pardon or “forgive,” see 21.8.
The anger of the LORD and his jealousy: for jealousy see 4.24; 6.15. Here, as often, the two nouns anger and jealousy can be translated as one phrase, a noun modified by an adjective: “the intense [or, furious] anger” (see in 1.27, where there are more than two terms).
Would smoke against that man: God’s anger is compared to a fire that flames out and burns and destroys. New Jewish Publication Society’s Tanakh translates “[the LORD’s] anger and passion [will] rage against that man.” Good News Translation has “will flame up against.” It is also possible to use a simile; for example, “The LORD will become furiously angry with that person, just like a flame that leaps up and burns him.”
The curses written in this book: see 28.58. The Septuagint expands considerably: “all the curses of this covenant written in this book of the law.” Contemporary English Version is similar, with “all the curses in The Book of God’s Law.”
Would settle upon him: that is, they would be applied to him, be laid upon him, or “fall upon him” (Good News Translation); or we may say “piling on him all the curses in….”
The LORD would blot out his name from under heaven: God will destroy the man and his family, so that there are no descendants left to carry on the family name (see 9.14; 25.19).
