Passage
Be ye ever mindful of his covenant, The word which he commanded to a thousand generations,
Be ye ever mindful of his covenant, The word which he commanded to a thousand generations,
1 Chronicles 16:13 Ye seed of Israel his servant, Ye sons of Jacob, his chosen ones.
1 Chronicles 16:14 He, Jehovah, is our God; His judgments are in all the earth.
1 Chronicles 16:15 Be ye ever mindful of his covenant, The word which he commanded to a thousand generations,
1 Chronicles 16:16 Which he made with Abraham, And of his oath unto Isaac;
1 Chronicles 16:17 And he confirmed it unto Jacob for a statute, Unto Israel for an everlasting covenant,
The verse centers on "ever", "mindful", "covenant", "word", "commanded", "thousand", and "generations". It is saying that the verse draws attention to "ever" and "mindful", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 14's "He Jehovah is our God His judgments..." into verse 16's "Which he made with Abraham And of...", so "ever" and "mindful" 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 "ever" and "mindful" with trust shaped by these words, not by a vague optimism outside the passage.
