SEV Biblia, Chapter 14:1
¶ En el año segundo de Joás hijo de Joacaz rey de Israel, comenzó a reinar Amasías hijo de Joás rey de Judá.
Clarke's Bible Commentary - 2 Kings 14:1
Verse 1. In the second year of Joash] This second year should be understood as referring to the time when his father Jehoahaz associated him with himself in the kingdom: for he reigned two years with his father; so this second year of Joash is the first of his absolute and independent government. - See Calmet.
John Gill's Bible Commentary
Ver. 1. In the second year of Joash son of Jehoahaz king of Israel reigned Amaziah the son of Joash king of Judah .] As Joash king of Israel began to reign in the thirty seventh of Joash king of Judah, ( 2 Kings 13:10), who reigned forty years, Amaziah must therefore begin his reign in the fourth of Joash king of Israel; this therefore must be understood of his second year after he reigned alone, for he reigned two or three years in his father’s lifetime.
Matthew Henry Commentary
Verses 1-7 - Amaziah began well, but did not go on so. It is not enough to do tha which our pious predecessors did, merely to keep up the common usage but we must do it as they did, from the same principle of faith an devotion, and with the same sincerity and resolution.
