Passage
Saying, Unto thee will I give the land of Canaan, The lot of your inheritance;
Saying, Unto thee will I give the land of Canaan, The lot of your inheritance;
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,
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 a few men in number, Of small account, and strangers in it.
1 Chronicles 16:20 And they went from nation to nation, And from one kingdom to another people.
The verse centers on "saying", "thee", "give", "land", "canaan", and "inheritance". It is saying that the verse draws attention to "saying" and "thee", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 17's "And he confirmed it unto Jacob for..." into verse 19's "When ye were a few men in...", so "saying" and "thee" 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 "saying" and "thee" with trust shaped by these words, not by a vague optimism outside the passage.
