For sure let me help you with these. The psalm 23 speaks about how a person may feel when having God as his shepperd, who takes care of everybody. The sermon on the mount explains different descriptions to explain many points from a biblical standpoint like what it means to be happy, how to deal with problems, acquire qualities that belong to a person who believes in god and not to worry too much about everyday problems. They are alike in the idea that God will provide what we need if we first look for his kingdom (e.g. Psalm 23:1 and Mathew 6:33,34). I hope this helps you
