“And when they prevailed over them, the Hagrites and all who were with them were given into their hands, for they cried out to God in the battle, and he granted their urgent plea because they trusted in him.” (ESV)
Here is another gem hiding in the tedium of the genealogies of 1 Chronicles (maybe they aren’t so tedious after all?…). The warriors of the Reubenites had their urgent plea to God granted because they trusted in Him. When we trust in the Lord and live out of that trust, we can go to Him in our times of need, in our battles, and He will be our help. If He was faithful to them as they trusted in Him, He will be faithful to us as well.
