Helaman does not know why they have not received reinforcements. He clearly assumes that there are sufficient men available to reinforce them, but he does not understand why the government doesn’t send them. Helaman fears “that there is some faction in the government, that they do not send more men to our assistance.” He will be proven correct.
Even though Helaman no longer has much faith in the government, yet ye maintains faith in God. God had delivered them, and will yet deliver them.
