'Summit' in the Bible

It happened that as David [was] coming up to the summit where he used to worship God, suddenly Hushai the Arkite [was] there to meet him. His coat [was] torn and dirt [was] on his head.

Now David passed a little from beyond the summit, and suddenly Ziba the servant of Mephibosheth [was] there to meet him [with] a pair of saddled donkeys; on them [were] two hundred loaves of bread and a hundred raisin cakes, [with] a hundred summer fruits and a skin of wine.

And you yourself said in your heart, 'I will ascend [to] heaven; I will raise up my throne above the stars of God; and I will sit on [the] mountain of assembly on the summit of Zaphon;

On that day, {its fortified cities} will be like the {abandonment of the wooded place and the summit}, which they deserted because of the children of Israel; and there will be desolation.
