Passage
Which He hath made with Abraham, And His oath--to Isaac,
Which He hath made with Abraham, And His oath--to Isaac,
1 Chronicles 16:14 He <FI>is<Fi> Jehovah our God, In all the earth <FI>are<Fi> His judgments.
1 Chronicles 16:15 Remember ye to the age His covenant, The word He commanded--To a thousand generations,
1 Chronicles 16:16 Which He hath made with Abraham, And His oath--to Isaac,
1 Chronicles 16:17 And He establisheth it to Jacob for a statute, To Israel--a covenant age-during.
1 Chronicles 16:18 Saying: To thee I give the land of Canaan, The portion of your inheritance,
The verse centers on "hath", "abraham", "oath--to", and "isaac". It is saying that the verse draws attention to "hath" and "abraham", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 15's "Remember ye to the age His covenant..." into verse 17's "And He establisheth it to Jacob for...", so "hath" and "abraham" 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 "abraham" with trust shaped by these words, not by a vague optimism outside the passage.
