Musar su Salmi 5:4

“Hashem, You hear my voice in the morning” (Tehillim 5:4). On the surface this verse is difficult to understand. Does Hashem hear only the voice of supplicants in the morning? Does He not hear our voices and listen to our prayers whenever we call out to Him? The explanation is as follows: When people pray at other times, their petitions are scrutinized first to see whether they are worthy of acceptance in light of their deeds. This is not the case, however, if one prays in the morning. Thus the Zohar relates in Parashas Balak (204a) that Rabbi Elazar, Rabbi Aba and the rest of the company were traveling along the road when Rabbi Elazar began a discourse with the verse, “Hashem, You hear my voice in the morning.”
