Cud is a term that is mentioned several times in the Bible, primarily in reference to animals and their digestive processes. Cud is defined as the food that has been regurgitated from the rumen, a large part of the stomach in ruminant animals such as cows, sheep, and deer. In the Bible, the mention of cud has both literal and figurative meanings.

In Leviticus 11:3-8, the Bible lists a number of animals that are considered unclean for consumption. One of the criteria for determining whether an animal is clean or unclean is whether it “chews the cud.” Specifically, the passage states, “Whatever divides the hoof and is cloven-footed and chews the cud, among the animals, you may eat.”
This passage is believed to refer to ruminant animals, which have a unique digestive system that allows them to break down and extract nutrients from tough plant material. These animals regurgitate food from the rumen and chew it again, a process known as rumination, before swallowing it again for further digestion. This allows them to extract more nutrients from their food than other animals can, making them valuable sources of protein and sustenance.
In addition to its literal meaning, the term “cud” is also used figuratively in the Bible to describe the process of reflecting on and meditating on God’s word. In Psalm 119:97, the psalmist writes, “Oh, how I love your law! It is my meditation all the day. Your commandment makes me wiser than my enemies, for it is ever with me. I have more understanding than all my teachers, for your testimonies are my meditation. I understand more than the aged, for I keep your precepts.”
In this passage, the psalmist compares the act of meditating on God’s law to the process of chewing the cud. Just as ruminant animals chew and re-chew their food to extract the maximum amount of nutrients from it, the psalmist suggests that reflecting on God’s word can help believers extract deeper meaning and understanding from it.
Similarly, in the book of Job, the character of Elihu uses the metaphor of cud to describe the way that wisdom and understanding are attained. In Job 34:2-4, Elihu says, “Hear my words, you wise men, and give ear to me, you who know; for the ear tests words as the palate tastes food. Let us choose what is right; let us know among ourselves what is good.”
Here, Elihu suggests that just as the palate can distinguish between different types of food, the ear can discern between true and false wisdom. He goes on to say in verse 3: “For the ear tests words as the palate tastes food. Let us choose what is right; let us know among ourselves what is good.”
Overall, the term “cud” in the Bible has both literal and figurative meanings. Literally, it refers to the regurgitated food that ruminant animals chew and re-chew to extract nutrients. Figuratively, it is used to describe the process of reflecting on and meditating on God’s word to extract deeper meaning and understanding. By using this term, the Bible draws on the natural world and the everyday experiences of its readers to help them understand complex spiritual concepts.
