Then they sat down to eat. And looking up they saw a caravan of Ishmaelites coming from Gilead, with their camels bearing gum, balm, and myrrh, on their way to carry it down to Egypt.
Genesis 37:25

When Joseph's brothers sold him to the Ishmaelites, why does the text tell us what the caravan was carrying? First, because their betrayal of Joseph is prophetic of Yeshua's death and burial, but also to remind us that there is always something good in every terrible thing that happens to God's faithful. All things work together for good to those who trust in YHWH.
