You asked

how do jesus's teachings on wealth and helping the poor echo or challenge this deuteronomy passage?

The passage, plainly, with room to sit with it.

Deuteronomy 15:7-8

“If there is with you a poor man, any of your brothers, within any of your gates in your land which Yahweh your God gives you, you shall not harden your heart, nor shut your hand from your poor brother; but you shall open your hand wide to him, and shall surely lend him sufficient for his need in that which he wants.”

Deuteronomy is presented as Moses' farewell speeches to the Israelites on the plains of Moab, just before they enter the promised land. This book re-states and re-interprets laws given at Sinai, preparing a new generation for life in their new home. Chapters 12-26 contain a lengthy legal code, including provisions for justice, worship, and social welfare, like this instruction about helping the poor among them.

What personal or communal boundaries might prevent us from opening our hands wide today?
