Passage
and the swan, and the pelican, and the carrion vulture,
and the swan, and the pelican, and the carrion vulture,
Leviticus 11:16 and the female ostrich and the male ostrich, and the sea-gull, and the hawk, after its kind;
Leviticus 11:17 and the owl, and the gannet, and the ibis,
Leviticus 11:18 and the swan, and the pelican, and the carrion vulture,
Leviticus 11:19 and the stork; the heron after its kind, and the hoopoe, and the bat.
Leviticus 11:20 Every winged crawling thing that goeth upon all four shall be an abomination unto you.
The verse centers on "swan", "pelican", "carrion", and "vulture". It is saying that the verse draws attention to "swan" and "pelican", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 17's "and the owl and the gannet and..." into verse 19's "and the stork the heron after its...", so "swan" and "pelican" belong inside that flow. In Leviticus context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "swan" and "pelican" with trust shaped by these words, not by a vague optimism outside the passage.
