The symbolism is very fitting. A shepherd cares for his flock, calls on his sheep who recognize his voice and provides them with safety and good pasture. The gathering of Israel is all about coming to Christ and entering into covenants with him. In return we get spiritual protection, rest and nourishment. One example to illustrate this is Ezekiel 34.
Ezekiel 34:11-13
Another interesting one from the Book of Mormon is found in Helaman 7:18-19
11 For thus saith the Lord God; Behold, I, even I, will both my sheep, and seek them out.
12 As a seeketh out his flock in the day that he is among his sheep that are scattered; so will I out my , and will deliver them out of all places where they have been in the and day.
13 And I will them out from the people, and them from the countries, and will bring them to their own , and feed them upon the mountains of Israel by the rivers, and in all the inhabited places of the country.
14 I will feed them in a good pasture, and upon the high mountains of Israel shall their fold be: there shall they in a good fold, and in a fat pasture shall they feed upon the mountains of Israel.
Notice that verse 18 is a reference to Psalm 95.18 It is because you have hardened your hearts; yea, ye will not of the unto the voice ; yea, ye have to anger against you. him19 And behold, instead of you, except ye will repent, behold, he shall scatter you forth that ye shall become meat for dogs and wild beasts.
Psalm 95 uses the "enter into his rest" term that was discussed in a series of posts a while back. I didn't really notice the sheep symbolism in Psalm 95 at the time, but it is interesting to note that Nephi-2 hints to this Psalm when talking about scattering and gathering. The gathering in a shepherd/sheep setting is coming to the pasture. This is synonymous with the "rest" or promised land that the Israelites would come to after wandering around in the wilderness, and the "mountains of Israel" in the Ezekiel quote.
7 For he is our God; and we are the people of his pasture, and the of his hand. if ye will , his

10 years long was I with this , and said, It is a people that do err in their heart, and they have not known my ways:

The temple connection of "enter into his rest" is discussed in this post. And thus we see (to borrow from Mormon) the recurring theme of the gathering of Israel as we come unto Christ through covenants, often taught through symbolism.
