### Biblical Occurrences & Contextual Analysis
The contexts in which `{{H3161}}` appears are distinct and powerful. In a devotional plea, the psalmist asks God to **unite** his heart, signifying a desire for a focused, single-minded devotion to fear the Lord's name [[Psalms 86:11]].

### Related Words & Concepts
Several related words help illuminate the concept of unity and its consequences:
* `{{H3824}}` **lêbâb** (heart): This word for the "mind" or "understanding" is the object of unity in [[Psalms 86:11]], where the psalmist prays for a **heart** that is united in its purpose to fear God.
* `{{H6951}}` **qâhâl** (assembly): This term for a "congregation" or "company" is what Jacob refuses to be united with in [[Genesis 49:6]], demonstrating that right association is critical.
* `{{H6900}}` **qᵉbûwrâh** (burial): Being denied a proper **burial** with others was a sign of great dishonor. In [[Isaiah 14:20]], the wicked king is not "joined" with them in burial, showing a final, consequential separation.
* `{{H2026}}` **hârag** (slay): The act of slaying, or killing with deadly intent, is the reason for the disunity commanded in both [[Genesis 49:6]] and [[Isaiah 14:20]], linking destructive actions to separation.

* **Singleness of Heart:** The word expresses a core spiritual goal: to have a heart that is wholly and singularly devoted to God, free from division and distraction [[Psalms 86:11]].
* **Moral Separation:** It establishes a clear principle of separation from evil. Being "united" with those who commit violence and destruction is a stain on one's honor and soul [[Genesis 49:6]].
* **Consequential Association:** The word implies that our actions determine our associations, both in life and in death. Wickedness leads to being dis-united from the community and its honors [[Isaiah 14:20]].
