SEV Biblia, Chapter 11:12
y en todas las ciudades, escudos y lanzas. Las fortificó, pues, en gran manera, y Judá y Benjamín estuvieron de parte de él.
John Gill's Bible Commentary
Ver. 12. And in every several city he put shields and spears , etc.] Furnished them with these and perhaps other pieces of armour, these being put for all, to defend themselves with against an enemy, and to annoy them: and made them exceeding strong ; so that they could not be easily taken: having Judah and Benjamin on his side : which tribes cleaved to one another, and to Rehoboam, and to the kings of the house of David, in later times, as well as to the true religion.
Matthew Henry Commentary
Verses 1-12 - A few good words might have prevented the rebellion of Rehoboam' subjects; but all the force of his kingdom cannot bring them back. An it is in vain to contend with the purpose of God, when it is made know to us. Even those who are destitute of true faith, will at times pa some regard to the word of God, and be kept by it from wrong actions to which they are prone by nature.
