'Searchings' in the Bible

the princes of Is'sachar came with Deb'orah, and Is'sachar faithful to Barak; into the valley they rushed forth at his heels. Among the clans of Reuben there were great searchings of heart.

Why abodest thou among the sheepfolds, to hear the bleatings of the flocks? For the divisions of Reuben there were great searchings of heart.

Give ear to my words, O Lord; give thought to my heart-searchings.
