They are inclosed in their own fat: with their mouth they speak proudly. They are enclosed in their own fat - Dr. Kennicott, Bishop Horsley, Houbigant, and others, read the passage thus: עלי חבלמו סגרו alai chablamo sageru, "They have closed their net upon me." This continues the metaphor which was introduced in the preceding verse, and which is continued in the two following: and requires only that עלי ali, "upon me," should began this verse instead of end the preceding; and that חלב cheleb, which signifies fat, should be read חבל chebel, which signifies rope, cable, or net. This important reading requires only the interchange of two letters. The Syriac translates it, shut their mouth: but the above emendation is most likely to be true.
They speak proudly - Having compassed the mountain on which I had taken refuge, they now exult, being assured that they will soon be in possession of their prey.
