The answer is: Araunah's

2 Sam 24:18-25 - Later the place where Solomon built the temple

In the intriguing narrative of 2 Samuel 24, we witness God directing King David to Araunah's threshing floor, a divine instruction loaded with significance. Threshing floors weren’t just plots of land; they were vital to ancient agricultural life, serving as places for processing grain, a symbol of prosperity and abundance. By choosing this location to establish an altar, the act also signified a levelling of David’s pride as he recognized his need for atonement, exemplifying true repentance.

What's fantastic is that Araunah wasn't just a random name thrown around. He was a Jebusite who acknowledges the weight of David’s request with great humility. Offered as he was to give David both the land and oxen for sacrifices, which illustrates a profound insight into generosity. David's reply, “I will not offer burnt offerings to the Lord my God that cost me nothing” (2 Samuel 24:24), emphasizes the heartfelt truth that sacrifices ultimately mean something when they come from personal resources.

Now, interestingly, this same location later becomes the site for Solomon's Temple, a landmark for Israelite worship serving as a significant spiritual and political hub for generations to come. This rotated connection beautifully directs our attention to how God can transform an everyday site into a holy ground—a little reminder that sometimes the most sacred choosings come unexpectedly, tangled up in our daily lives and struggles! This weaving of history and significance invites everyone on a journey—not just the privileged or societal elite—ultimately reminding us against a backdrop of grandeur that worship comes from the heart!
