וַיֹּ֨סֶף ע֥וֹד דָּוִ֛ד אֶת־כָּל־בָּח֥וּר בְּיִשְׂרָאֵ֖ל שְׁלֹשִׁ֥ים אָֽלֶף׃
At muling tinipon ni David ang lahat ng piling kalalakihan sa Israel, tatlumpung libo.
Rashi
All the chosen men of Yisroel, thirty thousand. Because they gathered for him when they crowned him in Chevron and [therefore] this was a second gathering [for Dovid] [Scripture] herefore says, "[Dovid] again gathered."
Tze'enah Ure'enah
“David again assembled all the picked men of Israel, thirty thousand” [6:1]. Many people of Israel assembled and they made David king in the city of Hebron. Now, when David wanted to move the Ark from the house of Avinadav to God’s house, he assembled thirty thousand young men.
