I Peter 2:3

Peter alludes to Psa 34:8. The first "tastes" of God's goodness are afterwards followed by fuller and happier experiences. A taste whets the appetite [BENGEL]. gracious--Greek, "good," benignant, kind; as God is revealed to us in Christ, "the Lord" (Pe1 2:4), we who are born again ought so to be good and kind to the brethren (Pe1 1:22). "Whosoever has not tasted the word to him it is not sweet it has not reached the heart; but to them who have experienced it, who with the heart believe, 'Christ has been sent for me and is become my own: my miseries are His, and His life mine,' it tastes sweet" [LUTHER].

The general exhortation to holiness is continued, and enforced by several reasons taken from the foundation on which Christians are built, Jesus Christ, and from their spiritual blessings and privileges in him. The means of obtaining it, the word of God, is recommended, and all contrary qualities are condemned (Pe1 2:1-12). Particular directions are given how subjects ought to obey the magistrates, and servants their masters, patiently suffering in well doing, in imitation of Christ (Pe1 2:13 to the end).

2:3 now that you have had a taste of the Lord’s kindness: The words are taken from Ps 34:8. Peter quotes this psalm again in 1 Pet 3:10-12.
