John Gill Commentary 1 Samuel 8:21

"And Samuel heard all the words of the people, and he rehearsed them in the ears of Jehovah." — 1 Samuel 8:21 (ASV)

And Samuel heard all the words of the people
Patiently, and without interruption; attentively heard them, took notice of them, laid them up in his memory; but gave no answer to them, but reported them to the Lord, as in the next clause:

and he rehearsed them in the ears of the Lord ;
privately, in a free and familiar manner, with great exactness, as they were expressed; this he did, not before the people publicly, but in secret prayer, seeking for direction what he should further do, or what answer he should return to them.
