"And it came to pass, from the day that the ark abode in Kiriath-jearim,
that the time was long; for it was twenty years: AND all the house of Israel
lamented after Jehovah." The first impression is that the two ideas are
consecutive. However, in the books of Samuel sometimes the indication of
periods and the narration of events sometimes go forwards and backwards (for
instance, 2 Samuel chapters 2 and 3).
So, in my case, my conclusion is based more in the chronology.
