The original text frequently used the simple past-tense form of the verb for the past participle. Here we have an example of had sprang, which was edited to had sprung in the third printing (in 1907) of the 1905 LDS edition. The conjoined began has also been interpreted as a past participle and therefore edited to begun in both the LDS text (in 1920) and the RLDS text (in 1953). It is possible, however, that this began could be interpreted as an instance of the simple past tense. For discussion of this second possibility, see under 1 Nephi 1:14.
This sentence in Jacob 5 is the only example in the text where the verb spring takes the past participial form. There are no instances of the simple past tense for this verb, only three examples of the base form spring. On the other hand, there are six cases of the past participial began and three of begun (see under Jacob 2:12 for the list). Also see past participle in volume 3 for a complete discussion of past participial forms in the original text of the Book of Mormon.
Summary: Restore the original verb forms sprang and began in Jacob 5:17.
