רֶ֫כֶשׁ

Based on the provided data, the Hebrew word רֶ֫כֶשׁ (re.khesh) is defined as a "steed." This suggests that the word is a term for a horse or a type of horse, possibly indicating speed, power, or nobility. The fact that it occurs 4 times in the Bible suggests that it holds a relatively limited, yet significant role in the text. Given its definition as a steed, it is likely that the word is used in contexts where strength, swiftness, or aristocracy are emphasized. However, without further context, it is unclear how specifically the word is being used in each of its 4 occurrences. The range of usage appears to be focused on describing a particular type of animal rather than a concept or abstract idea. In terms of significance, the word's limited occurrences may imply that it is not a central or defining concept in the Bible, but rather a specific detail that adds to the narrative or poetic texture of certain passages. Further analysis would be needed to understand the precise role of רֶ֫כֶשׁ in its respective contexts.
