What does Genesis 26:24 mean?
This conversation between the Lord and Isaac, which takes place on the very first night Isaac arrives in Beersheba (Genesis 26:23), echoes the Lord's words to Isaac at the beginning of this chapter (Genesis 26:1–5). This time, though, the Lord introduces Himself as "the God of Abraham your father." Throughout this chapter, the Lord seems intent on making clear to Isaac that His relationship with Abraham will continue in His relationship with Isaac. All of the promises and commitments remain.This time, the Lord adds a command to Isaac: Fear not. Perhaps Isaac is especially fearful and needs a reminder that trusting the Lord includes being less afraid of other people. This might have been reflected in Isaac's passive response to those who challenged his use of wells in the Valley of Gerar (Genesis 26:17–22). It brings to mind his fearful lie about his relationship to Rebekah (Genesis 26:6–11).
The Lord also says again that His faithfulness to Isaac is something He will keep, in part, "for my servant Abraham's sake."
