'Materials' in the Bible

Then David said, "Solomon my son [is] a boy and inexperienced, and the house built for Yahweh [must be] exceedingly great in fame and splendor throughout every land. I will make preparations for him." So David provided abundant [materials] before he died.

The ones who were building the wall and the ones {who carried the materials} were carrying in one hand while doing the task, and with the other hand were grasping a weapon.
