“The Lord is not slacke cōcerning his promise (as some men count slacknesse) but is long-suffring to vs-ward, not willing that any should perish, but that all should come to repentance.”
1611 King James Version (KJV)
3:9 The Lord is not slow - As if the time fixed for it were past. Concerning his promise - Which shall surely be fulfilled in its season. But is longsuffering towards us - Children of men. Not willing that any soul, which he hath made should perish.
2Pe 3:9 The Lord is not slack concerning his promise. If the day of the Lord seems delayed, it is not due to slackness. But is longsuffering to us-ward. It is rather because God is long- suffering and is giving time to call the world to repentance. See 1Ti 2:4.
