Psalms 60:3

Thou hast shewed thy people hard things: thou hast made us to drink the wine of astonishment.

God shows His people hard things by causing them to pass through severe troubles and trials. The wine of astonishment pictures those troubles as drinking a bitter, disorienting wine that overwhelms with astonishment. That wine belongs among the harmful drinks associated with the table of devils. The hardships apply to the small company of believers in Singapore, whose faith through trial has gained them a banner to display for the truth, as the next verse states.
