The root ימן (ymn) isn't used in the Bible as verb. We only know it from the derivatives, which show up in all cognate languages:
- The feminine noun ימין (yamin), meaning right hand (Genesis 48:13) or right side (Exodus 14:22, Numbers 20:17), or the right of other parts of the body (thigh - Judges 3:16; eye 1 Samuel 11:2). The right hand was seen as the seat of one's power. Hence the many references to God's right hand (Exodus 15:6, Psalm 98:1, Matthew 26:64). The right hand also denotes the south or a southern direction (when facing east, which is the past - west is the future - Psalm 89:12). The country of Yemen thanks its name to this usage; literally it means South Land. In this same sense, the left hand came to denote the north. The name Benjamin is formed from this word
- The adjective ימיני (yemini), meaning on the right (2 Chronicles 3:17, Ezekiel 4:6 only). In about five locations in the Bible this word is used as ethnonym for the Benjaminites (1 Samuel 9:4, Esther 2:5)
- The verb ימן (yaman), meaning to go or choose the right (Genesis 13:10), or use the right hand (1 Chronicles 12:2).
- The adjective ימני (yemani), meaning right hand or right (1 Kings 7:21, Exodus 29:20).
- The feminine noun תימן (teman), meaning south (Job 39:26, Zechariah 9:14), south wind (Psalm 78:25, Song of Solomon 4:16). BDB helpfully explains that this noun should be interpreted as "that which is on the right hand".
