1 Samuel 8 New American Standard Bible (NASB) Israel Demands a King
8 And it came about when Samuel was old that he appointed his sons judges over Israel. 2 Now the name of his firstborn was Joel, and the name of his second, Abijah; they were judging in Beersheba. 3 His sons, however, did not walk in his ways, but turned aside after dishonest gain and took bribes and perverted justice.
After hearing an adverse report concerning his sons there is no record of them being upbraided & reproved either by Samuel or God.
In a similar incident the house of Eli was judged for the wayward behavior of his sons.Eli did try to remonstrate with his sons nonetheless a curse & death sentence was pronounced on his house
1 Samuel 2:22 NASB
22 Now Eli was very old; and he heard all that his sons were doing to all Israel, and how they lay with the women who served at the doorway of the tent of meeting.
Curse pronounced on his house
1 Samuel 2:32 NASB
32 You will see the distress of My dwelling, in spite of all the good that [s]I do for Israel; and an old man will not be in your house forever.
Eli reproved his sons
1 Samuel 2:2 NASB
2 Now Eli was very old; and he heard all that his sons were doing to all Israel, and how they lay with the women who served at the doorway of the tent of meeting. 23 He said to them, “Why do you do such things, the evil things that I hear from all these people?
Nevertheless a death sentence is pronounced on Eli's sons.
1 Samuel 2:34 NASB
34 This will be the sign to you which will come concerning your two sons, Hophni and Phinehas: on the same day both of them will die.
Samuel was well aware of what happened to Hophni & Phinehas yet he failed to reprove his sons also,yet no severe judgement is pronounced either on him or his sons.
Was God lenient on the house of Samuel?
