Contradiction with James 2:15-16
Unlike in 1 Samuel 30:12 where a stranger is provided food and water, these verses point out that it is ineffective faith to send someone away without giving them physical needs.

Contradiction with Proverbs 25:21
This verse encourages providing for enemies, contrasting the fear-driven motivation that might arise in situations like 1 Samuel 30:12 of giving sustenance to someone potentially hostile.

Contradiction with Matthew 25:42-43
In 1 Samuel 30:12, a stranger is given food and water, whereas these verses talk about neglecting to feed and care for those in need as neglecting Christ Himself.
Matthew 25:42-43: For I was an hungred, and ye gave me no meat: I was thirsty, and ye gave me no drink:
Contradiction with Luke 16:21
1 Samuel 30:12 describes someone being given food and revived, contrasting with this verse where Lazarus, a poor man, desired crumbs and received nothing.
Luke 16:21: And desiring to be fed with the crumbs which fell from the rich man's table: moreover the dogs came and licked his sores.
Contradiction with 1 John 3:17

1 John 3:17: But whoso hath this world's good, and seeth his brother have need, and shutteth up his bowels [of compassion] from him, how dwelleth the love of God in him?
