Here the 1837 edition replaced wouldst with wouldest, just like it replaced shouldst with shouldest earlier in verse 47 of this chapter. Here in verse 55, the 1852 LDS edition reverted to the original wouldst, but the RLDS text has here retained the two-syllable wouldest. As explained under 1 Nephi 20:5, the critical text will in each case of would(e)st maintain the earliest reading, thus wouldst here in Alma 30:55.
