American Scripture
To ponder means “to weigh mentally, think deeply about, deliberate, meditate.” Moroni used this very term as he closed his record:
“Behold, I would exhort you that when ye shall read these things … that ye would remember how merciful the Lord hath been unto the children of men … and ponder it in your hearts.”
