The second printing of the 1852 LDS edition introduced the singular bloodshed as a correction in the stereotyped plates. Except for the 1858 Wright edition (which derives from the 1840 Cincinnati/ Nauvoo edition), all subsequent editions of the Book of Mormon have had the singular bloodshed. As discussed under 2 Nephi 10:6, in each case we let the earliest textual sources determine the number for bloodshed(s). Thus here in Jacob 7:24, the critical text will maintain the plural bloodsheds.
Summary: Restore in Jacob 7:24 the original plural bloodsheds.
