As discussed under 1 Nephi 8:20, the more probable reading here is the word strait rather than straight, although straight will also work. The argument is based essentially on the fairly close parallelism between this passage and Matthew 7:14 (“and narrow is the way which leadeth unto life”); both 2 Nephi 33:9 and the Matthew passage refer to the path or way “which leads to life”. Also see the discussion under 2 Nephi 31:9.
