[10:8] 1 sn A quotation from Gen 2:24. The “two” refers to husband and wife, not father and mother mentioned in the previous verse. See the tc note on “mother” in v. 7 for discussion.
[13:25] 2 sn An allusion to Isa 13:10, 34:4 (LXX); Joel 2:10. The heavens were seen as the abode of heavenly forces, so their shaking indicates distress in the spiritual realm. Although some take the powers as a reference to bodies in the heavens (like stars and planets, “the heavenly bodies,” NIV) this is not as likely.
