Dwight: You are correct and I acknowledged that in an earlier post referring to dictionary.com. But once again, notice the examples of "stumbled" used in sentences in your Merriam-Webster.com reference:

If I counted correctly, there are 20 sentences and EVERY ONE is in the intransitive form. Just as the 99 times that a form of "stumble" is used in the Bible and ALL of those are in the intransitive form. If the transitive form is currently (and correctly) in use, then at least half of all the examples should be in that form. But how many times is the transitive form used? ZERO
Notice the 2nd section of sentences above labeled "Learner's definition of STUMBLE". In other words, if you wanted to teach someone who had never heard the word, the definition of STUMBLE, you could use the 4 examples that follow. Notice they DON'T EVEN MENTION the transitive use of the word. Why do you suppose that is?
Again, according to CHE (Charles Harrington Elster), who is apparently an expert on the English language, it's because the transitive form died out in the mid 1600's.
