SEV Biblia, Chapter 20:3
para que se acoja allí el homicida que matare a alguno por yerro y no a sabiendas; que os sean por acogimiento del vengador de la sangre del muerto .
John Gill's Bible Commentary
Ver. 3. That the slayer that killeth [any] person unawares, [and] unwittingly, may flee thither , etc.] Who through mere accident, and without design, killed a person, friend or foe, one of his own kindred, or a stranger, without any malice against him, or intention to take away his life: and they shall be your refuge from the avenger of blood ; from any of the relations of the deceased, who might be stirred up to avenge the blood of his kinsman on the slayer; (see Numbers 35:12).
Matthew Henry Commentary
Verses 1-6 - When the Israelites were settled in their promised inheritance, the were reminded to set apart the cities of refuge, whose use and typica meaning have been explained, Nu 35; De 19. God's spiritual Israel have and shall have in Christ and heaven, not only rest to repose in, but refuge to secure themselves in. These cities were designed to typif the relief which the gospel provides for penitent sinners, and their protection from the curse of the law and the wrath of God, in our Lor Jesus, to whom believers flee for refuge, Heb 6:18.
