1 Samuel 9

After the people requested that Samuel anoint a king, the Lord instructed Samuel to warn the people of the consequence of a king as -

"Samuel told all the words of the LORD unto the people that asked of him a king.
11 And he said, This will be the manner of the king that shall reign over you: He will take your sons, and appoint them for himself, for his chariots, and to be his horsemen; and some shall run before his chariots.
12 And he will appoint him captains over thousands, and captains over fifties; and will set them to ear his ground, and to reap his harvest, and to make his instruments of war, and instruments of his chariots.
13 And he will take your daughters to be confectionaries, and to be cooks, and to be bakers.
14 And he will take your fields, and your vineyards, and your oliveyards, even the best of them, and give them to his servants.
15 And he will take the tenth of your seed, and of your vineyards, and give to his officers, and to his servants.
16 And he will take your menservants, and your maidservants, and your goodliest young men, and your asses, and put them to his work.
17 He will take the tenth of your sheep: and ye shall be his servants.
18 And ye shall cry out in that day because of your king which ye shall have chosen you; and the LORD will not hear you in that day."  (Old Testament | 1 Samuel 8:10 - 18)

Nonetheless -

"Nevertheless the people refused to obey the voice of Samuel; and they said, Nay; but we will have a king over us;
20 That we also may be like all the nations; and that our king may judge us, and go out before us, and fight our battles.
21 And Samuel heard all the words of the people, and he rehearsed them in the ears of the LORD.
22 And the LORD said to Samuel, Hearken unto their voice, and make them a king."  (Old Testament | 1 Samuel 8:19 - 22)

What I find interesting as a king is selected, that Samuel follows much the same pattern we do in our day extending calls.  First, the Lord sets up the way as he arranges that -

"...the asses of Kish Saul's father were lost. And Kish said to Saul his son, Take now one of the servants with thee, and arise, go seek the asses."  (Old Testament | 1 Samuel 9:3)

And as they could not find the asses, Saul and his servant considered approaching Samuel for directions. At the same time -
 
"Now the LORD had told Samuel in his ear a day before Saul came, saying,
16 To morrow about this time I will send thee a man out of the land of Benjamin, and thou shalt anoint him to be captain over my people Israel..."  (Old Testament | 1 Samuel 9:15 - 16)

I have experienced that with the face of a member seems to remain in my mind.  Samuel wants to get to know Saul a little bit  first so he asks Saul to  -

"...go up before me unto the high place; for ye shall eat with me to day, and to morrow I will let thee go, and will tell thee all that is in thine heart."  (Old Testament | 1 Samuel 9:19)

There even a interview that took place for -

"...Samuel said to Saul, Bid the servant pass on before us, (and he passed on,) but stand thou still a while, that I may shew thee the word of God."  (Old Testament | 1 Samuel 9:27)

Saul was then called to be king.
