Passage
And hath confirmed the same to Jacob for a law, and to Israel for an everlasting covenant,
And hath confirmed the same to Jacob for a law, and to Israel for an everlasting covenant,
1 Chronicles 16:15 Be ye mindful always of his covenant; the word which he commanded to a thousand generations;
1 Chronicles 16:16 Even of the covenant which he made with Abraham, and of his oath unto Isaac;
1 Chronicles 16:17 And hath confirmed the same to Jacob for a law, and to Israel for an everlasting covenant,
1 Chronicles 16:18 Saying, Unto thee will I give the land of Canaan, the lot of your inheritance;
1 Chronicles 16:19 When ye were but few, even a few, and strangers in it.
The verse centers on "hath", "confirmed", "same", "jacob", "israel", "everlasting", and "covenant". It is saying that the verse draws attention to "hath" and "confirmed", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 16's "Even of the covenant which he made..." into verse 18's "Saying Unto thee will I give the...", so "hath" and "confirmed" belong inside that flow. In 1 Chronicles context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "hath" and "confirmed" with trust shaped by these words, not by a vague optimism outside the passage.
