In the Exodus introductory, it references verse 1:33, and 1:34. Exodus 1 ends at 22.

    12 By God's self-revelation, the Israelites were instructed in the sovereignty and majesty, the goodness and holiness, and the grace and mercy of their Lord, the one and only God of heaven and earth (see especially Ex 3; Ex 1:6; Ex 1:33; Ex 1:34). The account of the Exodus and the events that followed are also the subject of other major biblical revelation (cf. Pss 105:25-45; Pss 106:6-27; Ac 7:17-44; 1Co 10:1-13; Heb 9:1-6; Heb 11:23-29).

Thanks, we'll put this on the list. It'll be interesting to see who made this mistake: John MacArthur, Thomas Nelson Publishers, or us. :)
