SEV Biblia, Chapter 3:16
A Simn, al cual puso por nombre Pedro;
Clarke's Bible Commentary - Mark 3:16
Verse 16. Simon, &c.] See on Matt. x. 2, &c.
John Gill's Bible Commentary
Ver. 16. And Simon he surnamed Peter .] Or Cephas, which signifies a rock, or stone, because of his courage and constancy, his strength and fortitude, steadiness and firmness of mind: this name was imposed upon him, not at the time of his mission as an apostle; nor when he made that noble confession of his faith in Christ, as the Son of the living God, at which time this name was taken notice of; but when Christ first called him to be his disciple and apostle; (see John 1:42).
Matthew Henry Commentary
Verses 13-21 - Christ calls whom he will; for his grace is his own. He had called the apostles to separate themselves from the crowd, and they came unto him He now gave them power to heal sicknesses, and to cast out devils. Ma the Lord send forth more and more of those who have been with him, an have learned of him to preach his gospel, to be instruments in his blessed work. Those whose hearts are enlarged in the work of God, can easily bear with what is inconvenient to themselves, and will rathe lose a meal than an opportunity of doing good. Those who go on with zeal in the work of God, must expect hinderances, both from the hatre of enemies, and mistaken affections of friends, and need to guar against both.

Vincent's NT Word Studies
16. And Simon he surnamed Peter. Mark relates only his naming and not his appointment, leaving his appointment to be understood.
Robertson's NT Word Studies
3:16 {Simon he surnamed Peter} (epeqeken onoma twi simwni petron). The Greek idiom seems awkward, but it is not. Peter is in apposition with _name_ or onoma (accusative). this surname Jesus gave in addition (epeqeken) to Simon (dative case). Here qen is a direct reference to what is told in #Joh 1:42 when Jesus met Simon for the first time. Mark here reflects Peter's own words. Luke (#Lu 6:14) simply says "Whom he also surnamed Peter." See #Mt 16:18 for the full explanation of the name Peter, a Rock, Cephas.
