The meaning of the name 'Samuel'
The Semitic/Hebrew name Samuel (šĕmûʾēl) most likely means “his name is El” — i.e., “his name [the name that he calls upon in worship] is El” — although it was also associated with “hearing” (šāmaʿ) God (e.g., 1 Samuel 3:9–11). In the ancient Near East, the parental hope for one thus named is that the son (and “his name”) would glorify El (a name later understood in ancient Israel to refer to God); or, like the biblical prophet Samuel, the child would hear El/God (“El is heard”).
Mormon seems to be quite familiar with this meaning of the name, as his account of the actions of Samuel the Lamanite seem to swirl around the concept of "hearing."
Consider this example, from the early part of Samuel's sermon:
39 O ye people of the land, that ye would hear my words! And I pray that the anger of the Lord be turned away from you, and that ye would repent and be saved. (Helaman 13)
1 And now, it came to pass that there were many who heard the words of Samuel, the Lamanite, which he spake upon the of the city. And as many as believed on his word went forth and sought for Nephi; and when they had come forth and found him they confessed unto him their sins and denied not, desiring that they might be unto the Lord.
2 But as many as there were who did not believe in the words of Samuel were with him; and they cast stones at him upon the wall, and also many shot arrows at him as he stood upon the wall; but the Spirit of the Lord was with him, insomuch that they could not hit him with their stones neither with their arrows.
3 Now when they saw that they could not hit him, there were many more who did believe on his words, insomuch that they went away unto Nephi to be baptized.
4 For behold, Nephi was baptizing, and prophesying, and preaching, crying repentance unto the people, showing signs and wonders, working among the people, that they might know that the Christ must come—
5 Telling them of things which must shortly come, that they might know and remember at the time of their coming that they had been made known unto them beforehand, to the intent that they might believe; therefore as many as believed on the words of Samuel went forth unto him to be baptized, for they came repenting and confessing their sins.
6 But the part of them did not believe in the words of Samuel; therefore when they saw that they could not hit him with their stones and their arrows, they cried unto their captains, saying: this fellow and bind him, for behold he a devil; and because of the power of the devil which is in him we cannot hit him with our stones and our arrows; therefore take him and bind him, and away with him.
7 And as they went forth to lay their hands on him... (Helaman 16)
7 ...behold, he did cast himself down from the wall, and did flee out of their lands, yea, even unto his own country, and began to preach and to prophesy his own people.
8 And behold, he was never heard of more among the Nephites; and thus were the affairs of the people. (Helaman 16)
The fulfillment of prophecy
24 And in one place they were heard to cry, saying: O that we had repented before this great and terrible day, and then would our brethren have been spared, and they would not have been burned in that great city Zarahemla.
25 And in another place they were heard to cry and mourn, saying: O that we had repented before this great and terrible day, and had not killed and stoned the prophets, and cast them out; then would our mothers and our fair daughters, and our children have been spared, and not have been buried up in that great city Moronihah. And thus were the howlings of the people great and terrible. (3 Nephi 8)
